Why should you use LAW tool?

When SAP informs you about an upcoming audit, this notice will include a request to provide your license usage information (the so called measurement request).  In this notice, SAP will inform you that the necessary tasks should be carried out with the SAP USMM program measurement and that you are recommended to use the SAP License Administration Workbench (LAW) to consolidate the relevant data. But do you have the knowledge and/or resources to make use of the LAW tool in an effective manner?

In our day to day practice we see many end users being puzzled about the concept and use of LAW. Some believe that it’s a license optimization tool, whereas others are convinced that it is only an administration tool.

In this article we will explain that the truth lies somewhere in the middle. Let us however first explain a number of basic concepts of the SAP systems measurement request.

How to measure

Most SAP customers receive an annual measurement request in which they are asked to perform the measurement of the SAP relevant systems. This ‘measurement request’ is nothing else but an actual license audit. This is a contractually agreed procedure that SAP customers must comply with. SAP provides you with a measurement program (USMM) that needs to be run on all your systems that are required to be included in your measurement. The results of the measurement are presented in the USMM measurement log files reports. Many end users think that the job is done as the measurement is concluded; without making use of the LAW tool, they send the USMM log file reports back to SAP. This is where things often go wrong.

 Why USMM is not enough

From SAP’s perspective it is your responsibility to review the results of the measurement, before submitting them to SAP. This is why it is absolutely critical to do your due diligence, not just on the technical side, but also with regard to contractual terms and conditions. Failing to understand SAP’s administration and procedure can cost you a lot of money that often can easily be saved.

To get a better understanding of how USMM works:

  • USMM only delivers the number of users with allocated named user license types and system supported engine measurements.
  • USMM does not recognize the connection between the license type and a given user’s competences. A user type is assigned by you as an end user. Individual users change roles over time, hence why you should perform regular reviews of the user types assigned to the individual users.
  • USMM does not recognize if the same user is working on multiple systems. As per SAP’s licensing terms, if the same user is working on multiple systems, the user should be counted only once according to the highest chargeable user type. However, USMM will not recognize them and it will list them per each system where they are classified.

LAW – is this the solution?

The LAW tool is mainly developed to avoid the double counting of individual users that may have access to multiple SAP installations. However, in order to be able to recognize the same individual user, correct and strict maintenance of the user criteria is required. In other words, your SAP administrator needs to assess if any one of the criteria (e.g. user’s email address, user ID, second and first name, or accounting number) are the same across all SAP systems.


Most likely, you want to pay only for what you use. The correct application and use of the LAW tool can save your organization a lot of money – even if you have a small or medium size business. A common misconception is that LAW is suited only for large companies, but our experience showed that this is not true.

In order to be certain that LAW works to your advantage, you are required to have the right knowledge available either in house through your SAP administrator or externally, through a hired SAP licensing expert company.

Make sure that you have the latest version of the tool, and that you are familiar with the potential errors. Have a solid understanding of how the tool is built and what functions are included, in order to maximize its potential.

Never share any data (whether it is LAW or any table export) to SAP, before you have a complete and accurate understanding of the meaning of the data. Stay in control of your software assets.
