Central User Administration

Question

Hello,
i want to realize a central user administration between two different SAP Systems.
In an testing environment i realized it between two logical systems with different mandants in one SAP system.
Now it should work between two hosts. For example SAP1 192.168.150.1 and SAP2 192.168.150.2. What are the differences i have to consider?

Answer 1

Lets take two systems with SIDs: “SA1” and “SA2”.
1. Cerate logical system name SA1MNDT100 on SA1 identifying mandant 100 on SA1
2. Assign it to mandant 100 in system SA1
3. Then on SA2 you have to tell that there is system named SA1MNDT100 ready for communication, so you must create logical system name SA1MNDT100 in SA2 but you don’t assign it to any mandant (because from SA2 point of view it is a remote system)
4. Then on SA2 create the RFC Destination with exactly the same name as your logical system defined in step 1 SA1MNDT100 pointing to hostname or ip of SA1/mandant 100 (this links remote logical system name with remote SAP system SA1)
5. Then on SA2 create different system name SA2MNDT500 indentifying mandant 500 on SA2
6. Assign it to mandant 500 in system SA2
7. Then on SA1 you have to tell that there is system named SA2MNDT500 ready for communication, so you must create logical system name SA2MNDT500 in SA1 but you don’t assign it to any mandant (because from SA1 point of view it is a remote system)
8. On SA1 cereate the RFC Destination named SA2MNDT500 pointing to SA2/manadt 500.
Hope this clarifies your doubt.
