STS user assignment via BADI not working

Hi everyone,

I'm using an implementation of the BADI UPS_NAME_RESOLVE to have SAP usernames mapped to cost centers in a hierarchy so they become their responsibility, and debugging shows that the usernames do get recognized by STS.

Unfortunately, the assignment doesn't seem to work. The only point where the BADI gets called is when assigning it to the hierarchy in STS, but if I leave the responsible person fields in the STS customizing blank, the STS welcome page for the planning users will not contain any planning tasks.

Am I missing something? Thanks for any help.

Regards,

Tilman
