• What is the cause and solution for SAP error message /SAPAPO/RRP_HEUR635 - No fixed pegging relationships were created ?

  The SAP error message /SAPAPO/RRP_HEUR635 No fixed pegging relationships were created typically occurs in the context of Advanced Planning and Optimization (APO) when running heuristics for production planning or detailed scheduling. This message indicates that the system was unable to create fixed pegging relationships between planned orders and their corresponding requirements.
  Causes:
  
  
  No Matching Requirements: There may be no requirements available that can be pegged to the planned orders. This can happen if the demand is not properly defined or if there are no open sales orders or planned independent requirements.
  
  
  Incorrect Configuration: The configuration settings for pegging relationships may not be set up correctly in the system. This includes settings in the planning book or the characteristics of the materials involved.
  
  
  Capacity Constraints: If there are capacity constraints that prevent the creation of pegging relationships, the heuristic may not be able to allocate resources effectively.
  
  
  Heuristic Settings: The specific heuristic being used may not be designed to create pegging relationships, or it may not be suitable for the current planning scenario.
  
  
  Material Status: The status of the materials involved (e.g., blocked, inactive) may prevent the creation of pegging relationships.
  
  
  Solutions:
  
  
  Check Requirements: Ensure that there are valid requirements (sales orders, planned independent requirements) available for the materials you are trying to plan. If necessary, create or adjust these requirements.
  
  
  Review Heuristic Settings: Check the settings of the heuristic you are using. Make sure it is configured to create pegging relationships and is appropriate for your planning scenario.
  
  
  Adjust Configuration: Review the configuration settings related to pegging in the APO system. This may involve checking the planning book settings, key figures, and the characteristics of the materials.
  
  
  Capacity Planning: Ensure that there are no capacity constraints that would prevent the creation of pegging relationships. You may need to adjust production capacities or scheduling parameters.
  
  
  Material Status: Verify the status of the materials involved in the planning process. Ensure that they are active and not blocked for planning.
  
  
  Run Heuristic Again: After making the necessary adjustments, run the heuristic again to see if the issue is resolved.
  
  
  Related Information:
  
  Transaction Codes: You may want to use transaction codes like /SAPAPO/RRP3 to analyze the planning situation and check the pegging relationships.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to this error message.
  Documentation: Review the SAP APO documentation for detailed information on heuristics and pegging relationships.
  
  If the problem persists after trying the above solutions, it may be beneficial to consult with your SAP support team or a consultant who specializes in SAP APO for further assistance.
