Credit exposure is not updated after reassignment of CC to CCA

Hi Gurus

we recently assigned company code A from Credit control area 001 to 002, then we did f.28 and RVKRED77 on customer ABC. however, for some reason when we check the exposure in FD33 with CCA 001, it is still showing an open delivery which belongs to a document in company code A.

Shouldn't all open transactions in company code A become irrelevant to credit control area 001 now?

Thanks.
