Preparation for the audit should begin long before an e-mail from SAP

This preparation includes a clear naming rule for users (the same users have the same user names in SAP Landscape) Clear user classification (create user – сlassify it) and so on.

Preparation. Steps.

Step 1. User classification (Measurement Systems)

Transaction – USMM

Transaction – SU01 or SU10

Review your license agreement and activate corresponding user types in transaction USMM.

For example SAP Professional User, SAP Worker User, etc

Look at SAP User types described here:

https://support.sap.com/content/dam/support/en_us/library/ssp/my-support/systems-installations/system-measurement/information-about-sap-system-measurement/user-classification/sap-user-types.xls

and classified users accordingly this document in transactions SU01 or SU10

Step 2. Client separation (Measurement Systems)

Transaction – USMM

Clients section.

Common rules – Exclude Client 000 from System Measurement

Step 3. RFC Settings (Solution Manager, Measurement Systems)

Step 3.1. Users creation

Transaction – SU01

Create in Measurement Systems communication users with role SAP_BC_LAW_COMMUNICATION

Step 3.2. RFC creation

Transaction – SM59 – RFC Destinations

Create a communication channel from Solution Manager to Measurement Systems with users credentials from Step 3.1

Step 4. Service activation (Solution Manager)

Transaction – SICF – HTTP Service Hierarchy Maintenance

Tree path – default_host > sap > bc > webdynpro > sap

Services – LAW3_WD_SLAT_MAIN, LAW3_WD_SLAT_MAIN, LAW3_WD_UC_START, LAW2_WD_ APPLICATION

[2] – Import measurement result via RFC or

[3] – Upload it manually

if you choose [2] you can perform the next substeps:

5. Upload XML file to SLAW2 in Solution Manager

Step 10. Combine Users in SLAW2 (Solution Manager)

Group Users (for example by User Name)

Step 11. Consolidate Users in SLAW2 (Solution Manager)

Start Consolidation

Step 12. Profitability Analysis in SLAW2 (Solution Manager)

When we try to Import System Overview, the system gives the error, "File ending .TXT is not supported." Help message says Message No. LAW2_MESSAGES204. The following file ending are supported: TXT, XML, and ZIP. Any ideas? Support ticket is open but we are waiting for a response.
