Hello Kannappan,
There is no certain definition for classification of users. SAP leaves the details to contract. If they are not defined in detail in your contract it is not certain.
You can find detail definitions of user types in below links. Especially in excell.
Let me give some brief info about some types. Check the docs for details please.
Developer user is clear. If users name is in DEVACCESS table it is counted as developer.
Professional User: If entering, updating in more than one module, displaying data, taking reports, Giving Approvals etc.
Limited Professional: Display data and give approvals etc. Managers can be in this clas.
MSS: Only for managers that are doing their own HR related works and giving HR related approvals etc .
ESS: Only for personnels that are doing their own HR related works.
Mostly SAP sends an xml file for all systems that needs to be measured according to your system data on SMP(service.sap.com). You must check all users in all clients of ABAP production and development systems. USMM checks all clients' users.
If you did not make any measurement before SAP uses Professional User type as default and assigns this to all unclassified users. Don't worry about these users you can reclassify them again.
1. I advise you to start gathering all users from all systems and clients to one excel sheet (can be seen below in picture) firstly, using SUIM user lists in each client . This distinct user list will be your scope for classification.
2. Then take users last 3 months "# of steps" using ST03N User statistics as seen below picture. There is no chance to take all 3 months you need to take one month and sum all 3 months # of steps. Or you can take the last month also. System measurement program looks for the last month as I know.
4. Clean all unnecessary users from all clients of all measurement asked systems. Be carefull when you are deleting. Check ST03N (from User stats part) for at least last 3 months usage and ask business also.
5. Unclassify all users that have user type B System or C Communication. These users must have been used for integrations between systems. DDIC, SAP* can be unclassified. Measurement program accepts these users as Technical Users. They are not measured.
6. Compare the number of distinct users on your excel and you contract. If # of users in your excel is more than in your contract this means you need to buy extra license. If # of users in your contract is more than you are in your license limit.
7. Classify users with the user types that are defined in your contract in your excel. Check # of steps that is collected in step 2. Higher the # of steps means professional user type, limited professional user type. You can check your contract how many users needs to be in each user types.
8. According to the classification you did in excel login to each system and client and classify users using USMM transaction.
9. Run Sytem measurements. If system warns you about misclassifying, change classification of those user with the higher one and rerun System Measurement.
When you are running System measurement in USMM transaction system warns you if you classified user in lower ranks (eg: ESS User, Limited user etc) and if they are indeed higher degree users (eg: developer, Professional etc). That time you classify one upper degree user type and rerun system measurement.
If measurement gives no warning export the result to law file.
10. Choose one of your system as central system (can be solution manager). Use SLAW in central system and import xml file. Then import all of the export results of the systems obtained in step 10.
11. Combine all results, Consolidate them and if everything is okey, "Transfer Direcly to SAP"
That's all.
