In case in the useradmin of the J2EE are two DDIC users as below:


the supportdesk tool report an error:

" RED    Error while determining user mapping for DDIC user.

com.sapportals.portal.prt.runtime.PortalRuntimeException: Error while determining user mapping for DDIC user.  at  at  at<init>(  at  at ...  at$ Caused by: USER_AUTH_FAILED: Logonid "DDIC" is not unique!  at<init>(  at<init>(  at  at  at  at  at  ... 72 more Caused by: Logonid "DDIC" is not unique!  ... 79 more  Download support info and send it to SAP support to fix the issue -     "

To solve the symptom:

Please delete the DDIC on J2EE which is binded to the "UME Database".

The other DDIC user is already assigned to ABAP, it must be the default and activated user.
