EBS – r12.1.3 Error while entering the Final Process Date for an employee on End Employment form

Error message = APP-PER-52994: A value has been provided for a non-enable or non-existent descriptive flexfield segment

Is being thrown when trying to extend the FPD for 3 employees entered by 1 user. User was a temp who has no Person attached to the User account.

Other employees terminated with the same Leaving Reason and on the same date work fine – can extend the FPD.

I've looked at the Addt'l Periods of Service DFF, segment 20 and it was disabled. I re-enabled the segment but no luck.

I've looked at the DFF on the LU table of LEAV_REASON and segment 20 is enabled. I'm attaching a document with various screen shots to show where all I've looked.
