• What is the cause and solution for SAP error message M7511 - Referenced reservation was not created manually ?

  The SAP error message M7511, which states "Referenced reservation was not created manually," typically occurs in the context of inventory management and material requirements planning (MRP) when there is an attempt to process a reservation that was not created through the standard manual reservation process.
  Cause:
  
  Automatic Reservations: The reservation in question may have been created automatically by the system (e.g., through MRP runs, production orders, or other automated processes) rather than manually by a user.
  Incorrect Document Reference: The system may be trying to reference a reservation that does not meet the criteria for manual processing, leading to this error.
  Configuration Issues: There may be configuration settings in the system that dictate how reservations are created and processed, which could lead to this error if not set up correctly.
  
  Solution:
  
  Check Reservation Type: Verify the type of reservation that is being referenced. If it is an automatic reservation, you may need to adjust your process to accommodate it or create a manual reservation if required.
  Create Manual Reservation: If the process requires a manual reservation, create a new reservation manually using the appropriate transaction code (e.g., MB21 for creating reservations).
  Review Configuration: Check the configuration settings related to reservations in the SAP system. Ensure that the settings align with your business processes and that the system is set up to handle the types of reservations you need.
  Consult Documentation: Review SAP documentation or help resources for specific details on how to handle reservations and the implications of automatic versus manual reservations.
  Error Logs: Check the system logs for any additional error messages or warnings that may provide more context about the issue.
