Manage vendor bank account in company code level - Best practice

hi,

we have on our client several company codes, and we are thinking how to manage the vendor bank accounts in company codes level or in centeral level.

our problem with company codes level is that the vendor bank accounts define in a centeral level so technically with sap standard it is not possible. if anyone can tell me that this is possible i will be very happy to know.

in centeral level our problem is with the business process because of we do not have a person (functionalism ) that can be responsible for all the company codes, basically every company shoule be responsible for her vendors

please advice what is the best practice to manage vendor bank accounts in enviroment of several company code

regards,

meir
