• What is the cause and solution for SAP error message CN779 - Planned independent requirement &1 for material &2/&3 no longer exists ?

  The SAP error message CN779 indicates that a planned independent requirement (PIR) for a specific material no longer exists in the system. This can occur in various scenarios, particularly in the context of production planning and material requirements planning (MRP).
  Cause:
  
  Deletion of Planned Independent Requirements: The planned independent requirements may have been deleted or not created for the specified material.
  Change in Planning Parameters: Changes in planning parameters or settings may have led to the removal of the PIR.
  Time Period Issues: The PIR may have been defined for a specific time period that has already passed.
  Data Migration or System Changes: If there have been recent data migrations or changes in the system, it could lead to the loss of existing PIRs.
  Incorrect Material or Plant: The error may also arise if the material or plant specified in the error message is incorrect or does not exist.
  
  Solution:
  
  
  Check Planned Independent Requirements: 
  
  Go to transaction code MD61 (Create Planned Independent Requirements) or MD62 (Change Planned Independent Requirements) to verify if the PIR exists for the specified material and plant.
  If it does not exist, you may need to create it again.
  
  
  
  Review Planning Parameters: 
  
  Check the planning parameters in the material master (transaction code MM02) to ensure that they are set correctly and that PIRs are allowed for the material.
  
  
  
  Adjust Time Periods: 
  
  Ensure that you are looking at the correct time period. If the PIR was defined for a past period, you may need to create new requirements for future periods.
  
  
  
  Check for Deletions: 
  
  If the PIR was deleted, you may need to recreate it. Check with your team if there were any recent changes or deletions made.
  
  
  
  Verify Material and Plant: 
  
  Double-check the material number and plant in the error message to ensure they are correct. If there is a typo or incorrect reference, correct it.
