• What is the cause and solution for SAP error message /SAPAPO/RRP_HEUR631 - No fixed pegging relationships in the selection ?

  The SAP error message /SAPAPO/RRP_HEUR631 No fixed pegging relationships in the selection typically occurs in the context of Advanced Planning and Optimization (APO) when you are trying to run a heuristic or planning run that requires fixed pegging relationships, but none are found in the selection criteria.
  Cause:
  
  
  No Fixed Pegging Relationships: The primary cause of this error is that there are no fixed pegging relationships defined for the selected products or resources in the planning run. Fixed pegging relationships are necessary for certain heuristics to function correctly, as they dictate how demand is linked to supply.
  
  
  Selection Criteria: The selection criteria used for the planning run may not include any products or resources that have fixed pegging relationships defined.
  
  
  Data Configuration: There may be issues with the configuration of the master data, such as the product master or the location product master, where fixed pegging relationships should be defined.
  
  
  Solution:
  
  
  Check Fixed Pegging Relationships: 
  
  Go to the product master data and check if fixed pegging relationships are defined for the relevant products. You can do this in the transaction code /SAPAPO/MAT1 (Product Master) or /SAPAPO/LOC1 (Location Product Master).
  Ensure that the relationships are correctly set up between the demand (e.g., sales orders) and the supply (e.g., production orders or stock).
  
  
  
  Adjust Selection Criteria: 
  
  Review the selection criteria used in the planning run. Make sure that you are selecting products or resources that have fixed pegging relationships defined.
  
  
  
  Review Heuristic Settings: 
  
  Check the settings of the heuristic you are using. Some heuristics may require specific configurations or settings to work with fixed pegging relationships.
  
  
  
  Data Consistency: 
  
  Ensure that the master data is consistent and that there are no missing or incorrect entries that could affect the pegging relationships.
  
  
  
  Run a Different Heuristic: 
  
  If fixed pegging is not a requirement for your planning scenario, consider using a different heuristic that does not rely on fixed pegging relationships.
  
  
  
  Related Information:
  
  Documentation: Refer to SAP Help documentation for more details on fixed pegging relationships and heuristics in APO.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as /SAPAPO/RRP3 (Interactive Planning) and /SAPAPO/HEUR (Heuristic Planning) for further analysis.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues or provide updates related to this error message.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
