Invoices posted in EUR doc. curr , while payment is in local curr.(by exchange rate on payment date)

[VladeJ]

Dear SAP experts, 

I'll try to expose this rather specific and complicated issue as best as I can. 

Due to legislation, there are few specific domestic vendors that are issuing invoices showing both amount in EUR curr. and amount in local curr. (Locl. curr. is calculated as: amount in EUR x Exchange rate on doc date). Exchange rate is updated daily in SAP (as M) and is different each day. Invoice is posted in EUR as doc curr., and SAP picks exchange rate from document date, to post amount in locl. curr.

Issue is arising when payment comes, as request is following: Payment needs to be done using Exchange rate from date of payment, which is always different from document date exch. rate (Payment amount: amount in EUR x exchange rate on payment date). As a consequence F110 can not be used for payment, but is manually managed outside of SAP, and wish is to have it through F110.

Hope you will understand the request.

Thanks for any comment on this.
