GRC AC 10 - PSS: Password reset failed: no valid Email-id maintained for user id

Hello SAP-Experts,

i have some issues with the Password Self-Service (PSS).

I'm on GRC 10.0 SP12.

I have 2 Plugin/backens systems: the GRC box my himself and another ERP6.0, were GRCPINW SP12 is installed.

My issue:

I have registered the Security Questions.

In step 1 I answer the questions -> in step 2 I select a backend system.

When I submit the PSS action, the error " Password reset failed: no valid Email-id maintained for user id" appears and nothing happens.

Thanks in advance for your help 😊
