Multiple APP run's for same vendor

Dear Friends,

I would like to know whether it is possible to do multiple payment proposals for a vendor on same dates.

here is the scenario:

Each business area would like to creat and edit payment proposals for the same dates, for ex: Run date is 1.1.08, next payment date will be 02.01.08 and schedule the actul payment run on say 03.01.08.

The actual payment runs will be processed by different paying coc.ode on 03.1.08

so for a given vendor say we have 2 open items which are due for each business area. I tried giving Business area in free selections .

when I try to create a secong payment proposal system gives me the message saying no payment proposal found for the co.code Message nO.FZ349

Yes it does makes sense to this meesage in the sense system wants to check that no invoice is paid twice by mistake.

But my question is since I am restricting open items by Busines area in the selection parameters itself shouldnt that be considered by system.

Hope I am clear.

Please let me know your inputs on the same.

Points assured for useful replies.

Thanks,

Vamsi
