• What is the cause and solution for SAP error message /SAPAPO/DM_SCHEDFAIL064 - Fixed pegging was broken - min. edge ?

  The SAP error message /SAPAPO/DM_SCHEDFAIL064 indicates that there is an issue with fixed pegging in the context of demand management and scheduling within SAP Advanced Planning and Optimization (APO). Specifically, the message "Fixed pegging was broken - min. edge" suggests that the system encountered a problem while trying to maintain the fixed pegging relationships between demand and supply.
  Cause:
  
  
  Fixed Pegging Relationships: Fixed pegging is used to link specific demand to specific supply. If the pegging relationships are broken, it can occur due to:
  
  Changes in demand or supply quantities.
  Changes in the production schedule or availability of resources.
  Constraints in the planning process that prevent the system from fulfilling the pegging requirements.
  
  
  
  Minimum Edge Violations: The "min. edge" part of the message indicates that there is a violation of the minimum edge constraint, which could mean that the system is unable to allocate the minimum required quantity of supply to meet the demand due to the pegging rules.
  
  
  Solution:
  
  
  Check Demand and Supply: Review the demand and supply data to ensure that they are correctly defined and that there are no discrepancies. Look for:
  
  Changes in demand that may not have been accounted for.
  Supply shortages or changes in production schedules.
  
  
  
  Review Pegging Relationships: Analyze the pegging relationships to ensure they are still valid. You may need to:
  
  Re-establish the pegging if it has been broken.
  Adjust the demand or supply quantities to ensure they align with the pegging requirements.
  
  
  
  Adjust Planning Parameters: If the issue persists, consider adjusting the planning parameters related to fixed pegging and minimum edge constraints. This may involve:
  
  Modifying the minimum edge settings in the planning book or configuration.
  Reviewing the planning strategy and adjusting it to better accommodate the current demand and supply situation.
  
  
  
  Run the Planning Process Again: After making the necessary adjustments, re-run the planning process to see if the error is resolved.
  
  
  Consult Documentation and Support: If the issue continues, refer to SAP documentation for further insights or consider reaching out to SAP support for assistance.
  
  
  Related Information:
  
  Transaction Codes: You may want to use transaction codes like /SAPAPO/DM to access demand management or /SAPAPO/SC for supply chain planning to analyze the data.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  Training and Documentation: Ensure that users involved in demand planning and scheduling are trained on the implications of fixed pegging and how to manage it effectively.
  
  By following these steps, you should be able to identify the root cause of the error and implement a solution to resolve it.
