SAP user measurement consolidation for multiple systems: SLAW

This blog will explain how to consolidate multiple SAP user measurements into 1 combined measurement using the SLAW tool.

Questions that will be answered are:

  • How to use the SLAW tool?
  • Which options and help does it bring for consolidation of user measurement?
  • How to consolidate if users have different user ID’s across the systems?


The SLAW tool has a successor in the SLAW2 tool. See this blog to see how SLAW2 works.

Preparation of consolidation

In each of the systems where you have run USMM user measurement, you have to export the data in the LAW file format. To do this go to USMM and select menu option System Measurement and Export to LAW file:

Export of LAW file

Save as local file is the most common and easy option. Repeat this for all your systems.

LAW consolidation

You need to select one system for consolidation. This can be your main ECC productive server or for example your solution manager system.

In the consolidation system start transaction SLAW:

SLAW start screen

The consolidation process consists of 4 steps:

  1. Load all the LAW files
  2. Combine the users
  3. Consolidate
  4. Send consolidated results

First load all of your LAW files, before going to the user combination.

In the step Combine Users you have several options to combine the users:

Combine users

The best option for your consolidation is dependent on the differences per system. If you user name is the same per system, then this is good option. If the username is different per system, but your email is kept consistent per system, then this is a better option. Last resort is to do by name.

After the combination you can start the consolidation. Result of the consolidation for test users on name looks as follows:

Consolidation on name

If you see cleansing opportunities, do use them. After the cleansing start USMM again, export LAW file and rerun the consolidation.

SAP user license measurement

This blog will explain about SAP user license measurement.

Important: this blog will explain in general terms. Your own company might have bit different agreements in their contract! Especially for larger companies no SAP contract is ever the same.

Questions that will be answered in this blog are:

  • How to measure users in the SAP system?
  • How can the USMM tool help in the clean up?
  • How does it work when I have same user in multiple productive system?

General tips and tricks on user measurements can be found in this blog.


In newer systems USMM is replaced by USMM2. For more information on USMM2 see this blog.

USMM user measurement tool

The user measurement tool USMM is the starting point. Start transaction USMM and you will come to the tool launch page:

USMM start screen

Important first step is to go to the tab User Types and activate the types according to your contract:

USMM active user types

Reminder: these types can be different company depending on the contract.

These activated types will now be visible in the SU01 License tab:

License tab in SU01

User classification check

In the USMM tool the first thing to do before running the measurement is to validate the user classification. From the USMM start screen click the user classification button. This will now list all the users in your system and the assigned or determined user classification:

User classification overview

If you want to change a classification you can do that in SU01 license tab, or directly from this screen by selection of the record(s) and pressing the Classify Selected Records button.

General rules for classification:

  • Background users (type B and S) typically count as Technical users
  • Non-classified dialog users will be set to Default (meaning SAP will count them as the most expensive type of users)
  • Locked users will be counted as well
  • Users outside of validity period will not be counted in the measurement
Deleted users and users outside of validity date will not be counted in the measurement, but the statistics of these actions will be!
If you execute regular clean up (every month or quarter) this will be seen in the statistics. If you do clean up just before the measurement it will be seen as well, and might lead to discussion. If you do monthly clean up discussions will end fast.

Executing the user measurement

After you have classified and checked all the users,you can start the user measurement in USMM by hitting the System Measurement button.

The USMM tool will now run by firing a huge amount of SM37 jobs. Wait until the jobs are finished (typically max 10 min runtime). Then you can see in USMM the result of the run in the log:

USMM run log results

The USMM tool will both do the user and automated engine measurement.

The USMM tool can be run as frequently as you want. The Send to SAP button is a real send and cannot be reverted.

Improving the USMM results

You can improve the USMM results via the User Data Analysis button:

User data analysis

Here there are several lists to help you find why certain elements are reported.

You can use this lists to find errors in the classification and do extra cleanup. Then you can rerun USMM before you submit the data to SAP.

Multiple productive systems

If you have multiple productive systems a lot of users will be present in both systems. Example: user is present in the core ECC system and runs reports in the BI system.

For the SAP user measurement you want to count the user only once.

To help you in this administration activate in USMM the Multi-Client/System type:

Multi client system user type

In SU01 license tab you can now refer to this type, and set the main system for user measurement:

Multi system user in SU01 tab

If you have multiple systems you run USMM per system. For consolidation of the runs per system you can use the SLAW tool (license administration workbench), or it successor the SLAW2 tool.

LUI License utilization information

The LUI (license utilization information) tool is an online SAP tool that has all the information on your on premise and cloud licenses information combined. For cloud the usage is automatically visible. For on premise systems you can upload the usage via the SLAW files. This can give you insights into under-consumption and over-consumption of licenses.
