Getting Error as Invalid Approver in AME for Purchase Requisition. FND User is valid.

Hi all,

I am getting error:

An invalid approver has been encountered in ame_engine.fetchRuntimeGroup:XXIFF_APPR_CDE&CDI_Girirajan& Mahesh. Please remove the invalid approver. Invalid approver originating system PER and originating system ID 77408.

I have checked that FND User records exists for this user.

And I also executed below query to see if workflow role is assigned and active to this user or no? ut there are multiple records, how to find which one is for AME Purchasing Reqs?

SELECT wf.user_name, wf.user_end_date, wf.*

FROM apps.WF_USER_ROLE_ASSIGNMENTS wf

where user_name like 'USERNAME';
