/SAPAPO/PAGT_HEUR039 - Details

• The SAP error message /SAPAPO/PAGT_HEUR039 Maximum limit of scheduling attempts reached - Infinite scheduling typically occurs in the context of Advanced Planning and Optimization (APO) when the system is unable to find a feasible solution for a scheduling problem after a predefined number of attempts. This can happen for various reasons, including:
  Causes:
  
  Data Issues: Inconsistent or incorrect master data (e.g., resources, production versions, or transportation lanes) can lead to infeasibility in scheduling.
  Capacity Constraints: If the capacity of resources is insufficient to meet the demand, the system may struggle to find a feasible schedule.
  Infinite Loop in Scheduling: The scheduling algorithm may be stuck in a loop due to conflicting constraints or settings.
  
  Configuration Issues: Incorrect settings in the planning area or heuristics can lead to scheduling problems.
  Demand and Supply Mismatch: If the demand exceeds the available supply or if there are constraints that prevent the fulfillment of demand, scheduling may fail.
