Warning "No address exists for user X"

Hello,

I have the following issue. Probably due to several upgrades from older R/3 versions to the newer ones, there is some residual information abount deleted user accounts that does not let me to process some background jobs (for example, RSSCD100_PFCG to find change documents for roles)

without manual intervention whihc is required becaue I get warnings of the type:

"No address exists for user X142932"

May be there is something left out in some tables that causes this issue, but I do not know where to look.

Any help in resolving this issue will be greatly apprciated.

thanks

Galina
