What are the prerequisites of SAP LAW tool?

SAP prerequisites law tool

In one of our previous articles, we introduced you to the concept and purpose of SAP’s License Administration Workbench (LAW) tool. In this article, we will dive deeper and discuss the different prerequisites of using this LAW tool. What are the technical and operational conditions that need to be met in order to make use of the LAW tool? Before we start, let’s briefly recap what the LAW tool actually is.

End users can make use of the SAP LAW tool to consolidate their systems measurement reports in a central system. In practical terms, this means a tool that recognises when the same users work on multiple systems. In doing so, the tool counts multiple users over different SAP systems only once, hence avoiding double counting.  In addition, LAW determines user license types as per the agreed terms and conditions. As an example: it ‘understands’ that Limited Professional User license rights are included in the rights of a Professional User.

Can all SAP customers use LAW?

No, LAW tool is only included in the Basis/Web Application server. This means LAW is only available to end users with an SAP ERP Central Component (SAP ECC). SAP ECC is also known as SAP Enterprise Resource Planning (ERP). In order to access the tool, the transaction SLAW or LICENSE_ADMIN should be used.

What conditions need to be met to use LAW?

Central System

LAW should be used in the central SAP system (and not in the distributed systems) to obtain accurate results. The identification of the central system is essential. This is a technical procedure that requires in-depth knowledge on the part of the system administrator. The important point to remember is that the central system release must be SAP R/3 4.6C SP30 (or later).


All relevant systems (ABAP production and non-production systems) need to be measured with the USMM program prior to user consolidation with LAW. Depending on the version permitted (LAW 1.0 or LAW 2.0), there are different ways to upload measured systems into the LAW tool, including:

Only once all the files are correctly uploaded, the system consolidation and user reconciliation can begin.

Free of charge

SAP does not require its end users to purchase a license or pay any fees to access and/or use LAW. SAP’s standard contractual agreement specifically entitles its end users to use LAW. This is also applicable when licenses are no longer under an active software maintenance contract. End users without an active support contract should however bear in mind that no updates or technical support will be delivered (also not for LAW).


Accessing and using LAW requires you to fulfil several conditions. Once these conditions are met (and if the LAW tool is used properly), LAW provides good support during an (internal or formal) SAP license audit process.  LAW can bring a lot of added value towards SAP end users. Think for example about the possibilities to use the results for your finance and/or HR reporting.

SAP administrators do however often lack the in-depth knowledge and experience. Making use of LAW seems simple but is extremely prone to errors. Multiple SAP Notes may need to be implemented. Mistakes are easily made. In 95% of the cases, end users end up with usage reports coming from LAW, not reflecting the actual usage (and reporting a higher usage).
