ABAP short dump

Hi folks,

I had an interesting issue. Last week we went for a client refresh from PRD to QAS environment. that resulted in a short dump while accessing the HR masterdata using PA30 or PA20, the infotype screen is not appearing.

The error log gave this info:

program "/1PAPA/FEAT210P0021 " does not exist in the library. it is getting called from SAPLHRP3 I believe. I see no modifications done to this program in QAS.

What can be reason for it? How can this be corrected?

Thanks in advance for your inputs,

SK
