Measurement of developer licenses

Every year SAP measures the licenses. The developer licenses are the most expensive licenses and also the ones which are under continuous debate with SAP.

Questions that will be answered in this blog are:

  • What is a developer and why is it so hard to measure?
  • How can I go back to the DEVACCESS measurement on my non-S4HANA systems?
  • What are the complexities on S4HANA with measuring developers?

Developer definition

Most likely the definition in your contract clearly states developer is only for creation and changing custom code (Z code). And not for applying OSS notes. The measurement should follow the definition.

Developer measurement on non-S4HANA system

On a non-S4HANA based system, the developer key concept still exists. This means a developer key needs to be called off at sap support site for keys. This mechanism is hackable, but in the end in the system table DEVACCESS is filled with everybody who has filled in the keys.

SAP has given update notes on the USSM user measurement programs that use the S4HANA logic, which is described below.

By applying OSS note 3038370 – USMM2: Development Workbench Check alte Version wieder herstellen, you can revert back to the original way of working that measures entries in DEVACCESS table and changes to REPOSRC.

The measurement of developers has to run on the development system. For security reasons, you should delete all entries in DEVACCESS table in all non-development systems.

When a developer is leaving, you should also delete the corresponding entry in DEVACCESS table to avoid it from being counted in the license measurement.

Read this blog on the deletions of entries in DEVACCESS table.

S4HANA logic (or better no logic)

In S4HANA SAP removed the developer key (see this blog). In the USMM measurement program SAP has put in logic to measure a developer as everybody who creates a transport entry of type Workbench. Text from the word document attached to note 3038370 – USMM2: Development Workbench Check alte Version wieder herstellen:

"In the current version of the check all users are shown that have made an entry of type K (workbench request) or S (development/correction) in the field TRFUNCTION in the table E070 within the last year."

This means also the following actions are counted as developer:

  • Basis team applying OSS note
  • Consultant making a client independent customizing
  • Many more actions that lead to entries in workbench request

This logic of SAP does not make any sense. As customer you can have big debates with SAP on this.

It is really unclear why SAP is not simply checking the REPOSRC changes on S4HANA system done on Z code last year. This will simply give list of real changes done on custom code by whom. That would be fair measurement.

SAP, if you read this, you can take over this idea.

OSS notes with or without manual instructions

Some OSS notes have manual instructions to create SAP Z programs or to alter SAP objects. To avoid discussions with SAP, it is best if you carry out these instructions by an ABAP developers, rather than a basis consultant. Not only does the ABAP developer has a better clue on what the impact is, it also makes sure that the Z coding and changes to standard SAP are registered in the system and transport on the ABAP developers name. This will avoid discussions on developer licenses.

If basis applies the automatic OSS notes, these are not core custom developments. Check if these are counted by the measurement program. Then check the definition in your contract. Most likely the definition in your contract clearly states developer is only for custom code (Z code). And not for applying OSS notes.

SSCR key listing and developer license

You can run program RSUVM080 to quickly get overview of developer SSCR keys in development system or view in table DEVACCESS. MOre on RSUVM080 in this blog.

LUI: license utilization information

The LUI (license utilization information) is a new tool provided by SAP to help you better manage the insights into your current utilization.

Questions that will be answered in this blog are:

  • How do I use the LUI tool?
  • Where do I find more information on the LUI tool?
  • Does the LUI tool work for on premise systems and cloud systems?

Use of the LUI tool

The LUI tool is part of the support pages of SAP and can be reached using this link.

Open opening the link and logging on, you start with the overview screen:

As you can see the overview is both for On Premise as well as Cloud based solution licenses.

You can zoom into the details per license to see the trend:

This can help you to detect since when (and then you will check why) you are crossing the line of having utilized too much. This enables you to either take actions to go back, or simply procure more licenses.

For the SAP cloud products, the actual usage is automatically added by SAP. If you want to add usage data for the on premise systems, you will need to upload the LAW files.
