• What is the cause and solution for SAP error message /SAPAPO/RRP_HEUR636 - No fixed pegging relationships were deleted ?

  The SAP error message /SAPAPO/RRP_HEUR636 No fixed pegging relationships were deleted typically occurs in the context of Advanced Planning and Optimization (APO) when running heuristics for production planning or scheduling. This message indicates that the system did not find any fixed pegging relationships to delete during the execution of the heuristic.
  Cause:
  
  No Fixed Pegging Relationships: The primary reason for this error is that there are no existing fixed pegging relationships in the system for the specific planning object (like a production order or a planned order) that the heuristic is trying to process.
  Incorrect Configuration: The configuration of the planning scenario may not be set up correctly, leading to the absence of pegging relationships.
  Data Issues: There may be issues with the master data or transaction data that prevent the creation of pegging relationships.
  Heuristic Settings: The heuristic settings may not be aligned with the current planning requirements, leading to no actions being taken.
  
  Solution:
  
  Check Pegging Relationships: Verify if there are any fixed pegging relationships defined for the relevant planning objects. You can do this by checking the relevant orders or stock levels in the system.
  Review Heuristic Settings: Ensure that the heuristic you are using is correctly configured to handle pegging relationships. You may need to adjust the settings or parameters of the heuristic.
  Data Validation: Check the master data (like material master, BOM, routing) and transaction data (like orders, stock levels) to ensure that everything is set up correctly and that there are no inconsistencies.
  Run the Heuristic Again: After making any necessary adjustments, run the heuristic again to see if it processes the pegging relationships correctly.
  Consult Documentation: Refer to SAP documentation or notes related to the specific heuristic you are using for any additional guidance or troubleshooting steps.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional context.
  Transaction Codes: Use transaction codes like /SAPAPO/RRP3 to analyze the planning situation and see the pegging relationships.
  APO Configuration: Review the configuration settings in the APO system, particularly those related to heuristics and pegging.
  Support: If the issue persists, consider reaching out to SAP support or your internal SAP team for further assistance.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
