SAPF181 /F.50 - Doc Splitting Active

WE are trying to book our discounts for Logistics Invoices (MIRO/RE) to a default Cost Center and then later, executing SAPF181 using F.50 to re-classify the Discount to the Cost Object from the PO Line item.

Issue

When I  attempt to run SAPF181/F.50   RECEIVE an ERROR MESSAGE that the Document Splitting is Active for Company Code we are using.

out there would be appreciated. 

Any suggestions you have would be so much appreciated.

Thanks so much!
