  The SAP error message KDFUE026, which states "Multiple assignment of the transaction is not permitted," typically occurs in the context of controlling (CO) or financial accounting (FI) when there is an attempt to assign the same transaction or document to multiple cost objects or cost centers, which is not allowed in the system.
