Create user for CPS in _ UPPER CASE LETTERS _ if using JSM on SolMan

Question

only create users for CPS in UPPER CASE LETTERS if using JSM on SolMan
Dear CPS Admins,
If you plan to use Job Scheduling Management (JSM) on SAP Solution Manager together with CPS by Redwood please always create any users in CPS only with upper case letters to avoid issues in the communication between SolMan and CPS.
The user creation for CPS is done in the UME (Java user administration, alias /useradmin).
Actually the CPS user itself is only created in CPS during the first logon.
Both CPS and the Java UME are case sensitive. So you can create users in uppercase, lowercase or mixed letters. But of course the system does still not allow duplicate names. So you can either create MUELLERP, MuellerP or muellerp - but not multiple of them.
Now, if the SolMan communicates with CPS for Job Scheduling, the actual user name is taken in some kind of a "trusted RFC like" way and checked on the CPS system connected to the SolMan. If the current SAP user does not exist on CPS no activities are possible, neither in read mode (read existing CPS jobs) nor in write mode (change existing jobs or create new ones).
Unfortunately the Solution Manager transmits the current user name to CPS only in upper case letter. So if the CPS user was not created in UPPERCASE letters in CPS the communication will fail. Therefore, think about creating CPS users in UME only in UPPERCASE letters. Changing this later is difficult to impossible.
Best regards,
Peter

hi,
I tried to reproduce your issue but I was not able to create a UME user with lower case letters.
UME automatically converted the user name into upper case after saving. So even if I enter "cps" as user name UME stored the user name as "CPS".
(maybe that happend because of the existing SU01-UME integration in our SolMan system)
If UME would be case sensitive I would expect that it is possible to create the user "CPS", "cPs" and "cps".
Regarding the SolMan-CPS connectivity:
Transaction SU01 allows only upper case letters (in user name and alias). Since you're starting from an ABAP system only user names with upper case letters are supported. It's a technical constraint of the ABAP user management that user names consist of upper case letters only.
Kind regards,
