• What is the cause and solution for SAP error message /SAPAPO/SDP_TLBGUI012 - Order must not be changed because it is known in OLTP system ?

  The SAP error message /SAPAPO/SDP_TLBGUI012 indicates that an order cannot be changed in the Advanced Planning and Optimization (APO) system because it is already known in the Online Transaction Processing (OLTP) system. This typically occurs in scenarios where there is a synchronization between the APO and the OLTP systems, such as SAP ERP.
  Cause:
  
  Data Synchronization: The order in question has been updated or changed in the OLTP system (like SAP ERP), and the APO system is not allowed to make changes to it until the synchronization is complete.
  Locking Mechanism: The order may be locked in the OLTP system, preventing any changes from being made in the APO system.
  Order Status: The order might be in a status that does not allow changes, such as being completed or delivered.
  
  Solution:
  
  Check Order Status: Verify the status of the order in the OLTP system. If it is in a status that allows changes, you may need to unlock it or change its status.
  Synchronization: Ensure that the data synchronization between the OLTP and APO systems is functioning correctly. You may need to run the relevant background jobs or transactions to synchronize the data.
  Wait for Update: If the order is currently being processed in the OLTP system, you may need to wait until the processing is complete before attempting to make changes in the APO system.
  Manual Intervention: If necessary, you may need to manually intervene in the OLTP system to make the required changes and then re-synchronize with the APO system.
  Consult Documentation: Refer to SAP documentation or support for specific instructions related to your version and configuration of the systems.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes in both the OLTP and APO systems, such as /SAPAPO/SDP_TLB for the APO system and standard transaction codes in the ERP system.
  SAP Notes: Check for any SAP Notes related to this error message for additional guidance or patches that may address the issue.
  System Logs: Review system logs for any additional error messages or warnings that may provide more context about the issue.
  User Permissions: Ensure that the user attempting to make changes has the necessary permissions in both systems.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP Basis or technical support team for further assistance.
