Account ID Automatically in Service Request

Dear Champs ,

Please guide me on below requirement on client ..

When any customer contact with the IC Agent and IC Agent will confirm his/her account through Account Identification (Screen Short 1). Now , my client wants that if they require to raise Service Request for our Customer after Confirming the relevant account through Account Identification . Then relevant BP Number of Customer should automatically available in Service Request Screen instead of they should manually select the BP No. (Screen Short 2).

As, in Interaction History Work Center , BP Number exist automatically after Confirm through Account Identification . (Screen Short 3). Similarly it should happen in Service Request Screen as well.

Please guide me that is there any standard solution available for that ? or it can be tackle through ABAP.

Thanks
