You explain my case
My company was bought by another company, and are migrating from a SAP system to another SAP, and we have documents created in the previous SAP to a different rate than that recorded in the new system , we customers need that the process to settle WBS elements, you can do to the exchange rate that brings the document, which is not the same that has the new system in that period.
I show one case:
Order created in the old SAP to rate of exchange of 2, 60, date of accounting: February 2010
In the new system the rate for the period February 2010 is 4.3
As i can do to settle at 2.60 and not to 4.3
Much i appreciate your attention in this case
I dont think you can migrate the posted items with a different exchange rate now.. that goes against the basic design of SAP... You cant change amounts of posted docs...
I would suggest you raise an OSS message to SAP and check if they have some SLO (Service Line Optimization) service in this regard...
Another option for you is to complete settlements in the old company code and upload the balances into the new company code with the desired exchange rate... i.e. I am asking you to follow the same process which is followed at the time of Go-Llive to upload the balances in FI
