  The SAP error message PK129, which states "Replenishment lead time in days is not possible," typically occurs in the context of inventory management and material planning. This error indicates that the system has encountered an issue with the replenishment lead time defined for a material or product in the system.
  Cause:
  
  Invalid Lead Time Configuration: The replenishment lead time may be set to a negative value or a value that exceeds the maximum allowed limit.
