error in exchange difference account due to document splitting characterstics for controlling

Hi Gurus,

Document splitting is activated for profit center. But when we are doing vendor payment, system is bringing cost center in exchange rate diff. account from original vendor invoice, which we dont want. We want one default cost center in that account. System is ignoring default cost center assignment.

I think this is because cost center field is assigned in document splitting characterstics for controlling. So if we dont want system to behave in such a way, can i delete cost center field from this characterstic. Will it have any other impact.

Or is there any other solution to this?????

Please reply back asap.

Thank You
