• What is the cause and solution for SAP error message OD129 - Line item &1 on document &2 is already assigned to this nominination. ?

  The SAP error message OD129 indicates that a line item in a document is already assigned to a nomination, which means that the system is preventing you from assigning the same line item to multiple nominations. This is a common issue in SAP, particularly in modules related to logistics, materials management, or project systems.
