SNOTE tips & tricks

This blog will give tips and tricks for the SAP SNOTE transaction. Questions that will be answered are:

  • How to update SNOTE itself?
  • How to check if there are new versions available for notes?
  • What is TCI?
  • Where to find tips on finding correct OSS notes?
  • How do I apply a note during upgrade in the shadow system?
  • What is the new SNOTE revamp?

If you are looking for way to check which OSS notes are needed, read the ANST blog: the automated notes search tool.

Notes for SNOTE itself

Also SNOTE itself can have bugs or has new functions. Download and implement most recent version of OSS note 1668882 – Note Assistant: Important notes for SAP_BASIS 730,731,740,750,751 to update SNOTE itself.

For the revamped SNOTE also note 3093855 – Note Assistant: Important SAP Notes for the Revamped Note Assistant is required to be updated.

Downloading and implementing new versions of OSS notes

SAP regularly updates its own OSS notes. To check in your system if there are new updates for OSS notes relevant to you go to transaction SNOTE. Then choose “Goto -> SAP Note Browser ->Execute (F8)”, and then choose “Download Latest Version of SAP Notes” in the application toolbar. This will download all the latest versions. Check for the status “Obsolete version implemented” in the implementation state column.

Issues with OSS note downloads

In rare cases OSS note download and extractions might fail.

Please check these OSS notes:

Activation of inactive objects after implementing OSS note

In rare cases after implementing an OSS note some of the ABAP objects are in an inactive state. To activate them, select the menu SAP note and then Activate SAP note manually.

Or you can run program SCWB_NOTE_ACTIVATE to activate the coding of the note:


See OSS note 1882419 – How to correct syntax errors.

TCI: transport based correction instructions

Transport based correction instructions contain notes that are larger than normal OSS notes. This tool leverages the SPAM transaction to apply these large packages.

Relevant OSS notes:

Start with reading the PDF document attached to OSS note 2187425: TCI for customer. This contains the exact instructions to enable TCI based correction instructions.

The TCI only recently has a rollback function. Please check if you can update/patch to the version where the rollback works. See the PDF document in OSS note 2187425 on the undo function.

Applying TCI note

There are 2 ways to upload TCI note.

Basis way: you will need SPAM access rights and 000 actions are involved. Upload the TCI file in SPAM in client 000. Then apply the note via SNOTE in main client. The note tool will ask you to confirm to use the TCI mechanism.

ABAP way: you will need SPAM access rights. In transaction SNOTE use menu option Goto / Upload TCI. After uploading the file, choose Decompress. Now apply the note via SNOTE. The note tool will ask you to confirm to use the TCI mechanism.

During the implementation, it can be that you are forced to delete all BI queues.

Transporting obsolete TCI packages

When you upgraded earlier to S4HANA or other recent version, some of the TCI notes might be obsolete. There is an issue moving this through the landscape. Read and apply the solution from OSS note 3116396 – How to Adjust Obsolete TCI Notes in Downstream Systems for the fix.

SNOTE revamp

In newer netweaver versions SNOTE is revamped. You can apply this version earlier if you want to use it. Read more on the SNOTE revamp in this blog.

Applying notes in shadow during upgrade

In rare cases you might need to apply and OSS note in the shadow system during a system upgrade. Basis team will usually use the SUM tool. Applying notes to shadow during upgrade can be needed to solve upgrade stopping bugs.

Always handle with care. If you are not experienced with upgrades, let a senior handle it.

The procedure to do this is described in OSS note 2207944 – How to implement a SAP note during System update using SUM (ABAP only).

Bug fixes for SNOTE

SNOTE itself might have issues:

SAP database growth control: HANA data aging

HANA data aging is a method to reduce the memory footprint of the HANA in-memory part without disturbing the end users. It is not reducing your database size.

This blog will answer following questions:

  • What is HANA data aging?
  • How to switch HANA data aging on?
  • How to set up HANA data aging for technical objects?
  • What about data aging for functional objects?

What is HANA data aging?

HANA data aging is an application method to reduce the memory footprint based on application data logic. It is not a database feature but an application feature. The goal of HANA data aging is not to reduce the database size (which it is not doing), but to reduce the actual memory footprint of the HANA in-memory database.

Let’s take idocs as example: the idocs that are processed ok you need to keep in database for an agreed amount of time before business or audit allows you to delete them. Lets say you can only delete after 1 year. Every action on idocs now means that full year of idoc content is occupying main memory. For daily operational tasks you normally only need 2 months of data in memory and rest you can accept that it will take bit longer to read from disc into memory.

This is exactly what data aging is doing: you partition the data into application logic based chunks. In this case you can partition the idoc data per month and only have last 2 months in active memory. The other 10 months are on disc only. Reading data of last 2 months is still fast as usual. When having to report on the 10 months on disc, the system first needs to load from disc into memory; will be slower.

To reduce database itself, you would still need to do data archiving.

Advantage of the data aging is that the more expensive memory footprint costs can be reduced in such a way that the end users are not hampered. Data aging is transparent for them. With data archiving the users will always need to select different transaction and data files.

How to switch on data aging?

To switch on data aging on system level you need to do 2 things:

  1. Set the parameter abap/data_aging to on in RZ11
  2. In SFW5 switch on the switch called DAAG_DATA_AGING

This only enables the system for data aging.

Data aging switch on for technical object: example for application logging

With transaction DAGADM you can see the administration status of the data aging object. You first see red lights that the objects are not activated for data aging.

Per object you have extra transactions (which unfortunately differ per object…) to set the retention times. For application logging this is transaction SLGR. Here we choose in this example to data age all log after 180 days:

The advantage of this tailoring is that you could only age some of the objects if you want.

The transaction and OSS note for each of the objects can be found on this SAP blog.

Next step is to setup partitions for the object. To do this start transaction DAGPTM and open the object you want to partition:

SBAL partitioning

Initial screen is in display mode. Hit change button. On the bottom right side hit the Period button (Selection Time Period). In the popup enter the desired start date, time buckets (months, years) and amount of repetitions:

Partition intervals

Now the partitions are defined. To execute the partitioning hit the execute button to start the partitioning in the background. Wait until the job finishes. Before running this on productive system check the runtime first on non-productive system with about same data size if possible.

After partitioning the screen should look like this:

Now we can activate the object in transaction DAGADM. Select the object and press the activate button. Popup appears to assign the object to existing data aging or new group:

The data aging run will be done per group.

To start the actual data aging run start transaction DAGRUN.

Here you can schedule a new run with the Schedule new run button.

To see the achieved results of the data aging go to transaction DAGADM and select the object. Then push the button View current/Historical data.

Functional data aging objects

Functional data archiving objects exist as well for Financial documents, sales orders, deliveries, etc. The full list and minimal application version can be found on this SAP blog.

Words of caution for functional archiving:

  • The technical archiving objects are more mature in coding and usage. They are used in productive system and are with lesser bugs than the technical objects
  • Before switching on a functional data aging object you need to prepare your custom ABAP code. If they are not adjusted properly to take the partitions with the date selections (or other application selection mechanism) into account all benefits are immediately lost. A Z program that reads constantly into full history will force a continuous read of historical partitions….

SAP database growth control: technical cleanup

This blog will explain about technical cleanup to reduce the SAP database growth and to regain control of it.

Questions that will be answered are:

  • How to run the standard SAP clean up jobs?
  • Where can I find full list of items that could be cleaned up?
  • How to run the cleanup of some common objects?
  • Database reorganization after cleanup?
  • How can I clean up old idocs?
  • How can I clean up old table logging?
  • How can I clean up old application logs?
  • How can I clean up old RFC logs?
  • How can I clean up old change pointers?
  • How can I delete workflow logging?
  • How can I archive workflows?
  • How can I delete SAP office documents?
  • How can I delete old audit log data?
  • How can I execute specific clean up for BI systems?
  • How can I execute specific clean up for solution manager system?
  • Many more…. use search for table name

This blog assumes you have followed the step in the blog to get insight into your fast growing SAP tables.

If you run ECC on HANA or S4SHANA check out this blog on data aging.

This blog focuses on technical data objects archiving and clean up by performing deletion. If you want to setup functional archiving, start reading this blog.

List of technical clean up items

A full list of all possible technical clean up items can be found in OSS note 2388483 – How-To: Data Management for Technical Tables. The chapters below describe the most common ones.

SAP standard clean up jobs

Using SM36 you can plan all SAP standard jobs (which include a lot of clean up jobs for spools, dumps, etc) via the button Standard Jobs.

By hitting the button Default scheduling in an initial system, or after any upgrade or support package, the system will plan its default clean up schedule.

SM36 standard job scheduling

S4HANA has different set up of standard jobs. See blog.

Clean up of old idocs

Idoc data is stored in EDI* tables. Largest tables are usually EDI40, EDIDS and EDIDC.

Old idocs can be deleted using transaction WE11.

Idoc deletion

In batch mode you can schedule it as program RSETESTD.

In the bottom of the selection screen are the technical options:

Idoc deletion technical settings

The idoc deletion job can fail if there is too many data to process. If they happens remove the 4 tick boxes here and use the separate deletion programs: RSWWWIDE, RSARFCER, SBAL_DELETE and RSRLDREL2. These 5 combined programs will delete the same, but run more efficiently. This procedure is also explained in OSS note 1574016 – Deleting idocs with WE11/ RSETESTD.

Also check these OSS notes:

Clean up of table logging

Table logging is stored in table DBTABLOG (general information on table logging can be found in this blog). Deletion can be done using transaction SCU3 and then choosing the option Edit/Logs/Delete, or by using program RSTBPDEL.

After you apply OSS note 2535552 - SCU3: New authorization design for table logging: new transaction code SCU3_DEL will be available.
DBTABLOG deletion

More background information: OSS note 2335014 – DBTABLOG | Reduce size. Instructions to set up periodic job: 2388295 – RSTBPDEL | Delete logs periodically.

Bug fix OSS notes:

Clean up of application logging

Application logging (SLG1) is stored in tables BALDAT and BALHDR (for general information on the use of the application log, read this blog). Deletion can be done using transaction SLG2 or by using program SBAL_DELETE.

The last options to fine tune the number of logs per job and the commit counter setting do not appear by default. Select menu option Program/Expert mode first.

Read more details in the FAQ note: 3039724 – BALHDR and BALDAT: Application Log tables size increases [FAQ].

The deletion logic on expired and non-expired logs is described in OSS note 195157 – Application log: Deletion of logs.

For setting up a dynamic variant, follow the instructions in OSS note 2936391 – Dynamic variant to remove logs with SBAL_DELETE.

Tuned setting for commit counter is described in OSS note 2507213 – SBAL_DELETE runs too long.

Bug fix notes:

Delete old RFC data

Old RFC data can be deleted using transaction SM58, selecting some data, then in the overview screen select the menu option Log File/ Reorganize. Or by starting program RSARFCER.

More background information in OSS note 2899366 – Huge entries in table ARFCSDATA.

In this note you can also read to check SMQ1 as well, since qRFC’s are also stored in ARFCSDATA table. See blog on qRFC’s.

To delete records with update errors as well, run program RSTRFCES. See notes 3095792 – Unable to delete entries from SM58 transaction and 3245070 – How to delete tRFCs with error “Update terminated” in SM58.

Optimization and bug fix OSS notes:

Delete old change pointers

Old change pointers occupy space in tables BDCP2 and BDCPS. You can use transaction BD22 or report RBDCPCLR/RBDCPCLR2 (3248987 – The difference between reports RBDCPCLR and RBDCPCLR2) to delete them.

Delete change pointers

Detailed description of all the options can be found in OSS note 2676539 – BD22 (Report RBDCPCLR) Options Explained.

MDG change pointers

If you are using MDG: it has its own set of change pointer tables (MDGD_CP_REP_STAT). Clean up transaction code is MDGCPDEL. Program for batch job clean up is RMDGCPCLR.

Background in OSS note 3075612 – MDG-DRF: Reducing table entry of MDGD_CP_REP_STAT.

Bug fix note:


Workflows are stored in many tables starting with SW*.

You can delete work item history with transaction SWWH or program RSWWHIDE.

Delete workflow item history

This clean up will only do the work item technical history and not the workflow itself. If workflow itself can be deleted or is to be archived is a functionality decision that the depend on the business and audit needs.

The workflow deleting program can create large amount of spools. If this is not wanted use the NULL printer.

If your business is using the GOS (generic object services) to see workflows linked to a business document, and they cannot retrieve the archived work item, please follow carefully the instructions in OSS note 2356250 – Not able to view archived workflows.

Workflow archiving

Workflow archiving can be done with archiving object WORKITEM (2578826 – Archiving Object WORKITEM – tables with deletion). For archiving setup read this blog. This note explains how to run the archiving of the WORKITEM object: 2157048 – Workflow Quick Start Guide to WORKITEM Archiving. Data display for the archived work items is explained in OSS note 2748817 – How to display Workitems from archive.

Only workflows of status Completed or Logically deleted (CANCELLED) can be archived (see OSS note 2311382 – Not all work items are archived). You can use transaction SWIA for mass logical deletion (see blog, and OSS note 2650820 – Mass complete work items manually). A custom program can be used for mass cancellation in batch mode (see blog).

If you run on HANA, read OSS note 3251001 – WORKITEM tables disk size not reduced after archiving.

Bug fix OSS notes:

Workflow deletion

If you want to delete the actual workflow you have to run program RSWWWIDE.

Take care that before deleting workflows you have checked that these are not needed for audit or financial proof. Some workflows will contain approval steps with a recording of who approved what at which time.

Orphaned workflow records

Run program RSWWWIDE_DEP to list and delete orphaned workflow records. See OSS notes 2971286 – Table SWW_PROPERTIES and 3144853 – SWWLOGHIST table size is increasing.

Large amount of documents in SAP inbox

If you have a large amount of items in your SAP inbox, you can delete them via program RSSODLIN. Background is in OSS note 63912 – SAPoffice: Delete user sessions.

Deleting SAP office documents

SAP office documents are stored in table SOFFCONT1, and can be deleted with program RSBCS_REORG. See note 966854 – Reorganization – new report. Note 988057 – Reorganization – information contains a very useful PDF document that explains what to do in cases that RSBCS_REORG is not directly can delete an SAP office document. In most cases you have to run a special program that breaks the link between the document and the data. After that is done you can delete the content. Extra explanation is in OSS note 1641830 – Reorganization of Business Communication Services data (RSBCS_REORG).

Test this first and check with the data owner that the documents are no longer needed.

For a full explanation on deleting SAP office documents (including all the pre-programs to run) and bug fix notes: read this dedicated blog on SAP office document deletion.

Migrating SAP office documents to content server.

Usually the business will not allow deletion of SAP office document (unless they are very old). You might be ending up with a SOFFCONT1 table of 100 GB or more.

In stead of deleting SAP office documents, you can also migrate them to a content server. Read more in this blog.

Change documents

Change documents do contain business data changes to business objects. If tables CDHDR and CDPOS grow very big, you start with an age analysis. You can propose to business to delete change documents older than 10 years. 10 years is the legal time you need to keep a lot of data. Deletion is done via program RSCDOK99. If business does not want to delete, but keep the data in the archive, you can use data archiving object CHANGEDOCU. Retrieval of archived change documents is via transaction RSSCD100.

Background in OSS note: 3103201 – CD: Archivierungsmöglichkeiten für die CDPOS.

Read this extensive blog on Change document data archiving.

Bug fix OSS notes:


See OSS note 3171193 – SMIMCONT1 table size is large to run in SE37 the clean up function module CLEAN_LANG_SMIMCONT1. This only cleans obsolete entries.

SYS_LOB tables

If you have large SYS_LOB tables, most likely these are occupied with attachments. Consider setup of SAP content server (see blog) and then migrate the documents from the SAP database to the content server (see blog).

To analyze SYS_LOB tables, follow the instructions in this dedicated blog.

LTEX table

LTEX table is used for storing ALV extracts data. Use program BALVEXTR to delete old entries. See OSS note 557772 – ALV extracts: Improving the BALVEXTR management report.

Clean up old Audit log data

You can schedule program RSAUPURG or program RSAU_FILE_ADMIN with the right variant to delete old Audit log data:

Before deleting audit log data, first agree with your security officer on the retention period. More on audit log in this blog.

Clean up of user role assignment data

If you have an older system, you will find that many users will have double roles assigned, or roles with validity dates in the past. This will lead to large amount of entries in table AGR_USERS. You can clean up by compressing this data with program PRGN_COMPRESS_TIMES. Read more in this blog.

Large WBCROSSGT table

Table WBCROSSGT is used to store the ABAP where used index. Might be large after upgrade. Use program RS_DEL_WBCROSSGT to delete and program SAPRSEUB to recreate the indexes.

Clean up of web service data

If table SRT_MMASTER is growing fast, it is time for clean up of web service data: see OSS note 2231932 – ESI – How to schedule the SAP_SOAP_RUNTIME_MANAGEMENT standard background job.

Clean up of BI data

For clean up of BI data please read this dedicated blog on clean up of BI data.

In the system that BI system extracts data from, you can run diverse cleanups:

Clean up for solution manager system

For clean up of a solution manager system, read this dedicated blog.

Clean up for SAP Focused Run

For clean up of a SAP Focused Run system, read this dedicated blog.

Updating statistics

If you are running Oracle database it is wise to include in technical clean up job as last step the online reorganization of tables or indexes using program RSANAORA. See blog.

Clean up non-used indexes

Oracle has a function called index monitoring to check if indexes are used at all.  You can use it to delete non-used indexes. See OSS note 105047 – Support for Oracle functions in the SAP environment.

Enque and lock table issue analysis

Enqueue and lock table issue analysis can be bit hard form time to time. They don’t regularly occur and when they do, they can have big system performance impact.

This blog will explain:

  • How to detect enqueue issues?
  • How to quickly analyze the enqueue issues?

Detecting enqueue issues?

Enqueue issues can be easily detected in SM50 and SM66 if work process get stuck long time with status ENQ.

First analysis on enqueue issues

The first analysis on enqueue issues can be done in transaction code SM12. From the menu now select the options Extra / Diagnosis and Extra / Diagnosis in Update. This will run the diagnostics on the enqueue handling.

Result looks like:

SM12 check enqueue in update

To get statistics on the enqueue processing, on the same SM12 start screen select the menu Extra / Statistics.

Deeper analysis on enque issues

For deeper analysis on the lock issues, you might need to switch to the detailed error handling part of SM12. This is a hidden feature. To switch it on you must have the correct authorization (S_ENQUE with ALL in the activities). Switching can be done by keying in the word TEST in the GUI command line (where you key in the tcodes and the /n etc).

Now you will see an extra menu called Error Handling.

From this menu you can directly launch program RSMONENQ_PERF via the menu option Error handling/Diagnosis environment. This programs will check the performance of the enqueue handling:

Result from program RSMONENQ_PERF

The Error Handling menu will also give you option to trace the enqueue processing.

Even more analysis is possible with the Enqueue Log Analyzer. See OSS note 3110596 – Analyze the enqueue scenario with enqueue log analyzer and kernel snapshot analyzer.

More backgrounds can be found in OSS note 2252679 – How to analyze an enqueue lock problem and OSS note 2126913 – ENQU: The enqueue log (specifically on the logging).

Troubleshooting for old locks: 2422483 – Troubleshooting old locks transaction sm12.

Large log file: 3254498 – Large number of entries in enqueue backup files.

High wait times: 3250533 – High “Waiting Time for Lock Operations” statistic in Enqueue Server Administration.

Not all locks are shown: 2795956 – SM12 does not list all locks.

Lock table overflow

Lock table overflow can happen when more locks are set by programs then the available allocated memory for the locks. In a normal system this will hardly occur. But during a conversion that is operating on massive amount of data (sometimes even using parallel jobs) this lock table overflow can happen. If it happens this will effect ALL users. They will get lock table overflow error and cannot save their work. More then enough reason to have large conversion tested first on a test system with production like sizing and settings.

The FAQ note on lock table overflow is: 552289 – FAQ: R/3 lock management.

What can be done about lock table overflow?

Provided you have checked your system sizing, you can increase the lock table memory by increasing the parameter enque/table_size. More background read OSS note 1565578 – Lock Table Overflow and OSS note 13907 – System error in the block handler, overflow lock table.

Before increasing make sure to have read these two OSS notes on the lock table: OSS note 746138 – Analyzing lock table overflows and OSS note 746138 – Analyzing lock table overflows.

If you are running an older ECC system, the lock table settings in the profile parameters might be set quite low. Newer upgraded ECC system can handle much higher values of the enque/table_size parameter.

Top capacity users

In SM12 you can select menu option Extra / Top Capacity Used / Current or History to find the top users of locks. Background: 2138377 – Output delivered by “Top Capacity Used” menu in SM12.
