CBIH82 - Work Area Custodian

Hi Experts,

I am not maintaining Work Area Custodian in my Work Area "CBIH02" transaction, but still the work area custodian person appears in transaction "CBIH82" while entering the inc/ac report.

I debugged using ABAPer as it may be hard coded somewhere using customization, still there are no results.

Are there any from from functional perspective that it can be maintained other than "CBIH02" transaction ?

Please suggest your replies.

Regards
