  The SAP error message ATPC018 indicates that there is no availability check for a specific item in the context of supply assignment. This typically occurs in scenarios where the system is unable to perform an availability check due to configuration settings or the nature of the item being processed.
  Cause:
  
  
  Item Category Configuration: The item category of the material may not be configured to allow for availability checks. This can happen if the item is set up as a non-stock item or if the item category does not support availability checks.
  
  
  Supply Assignment Settings: The supply assignment settings for the material may not be properly configured. This can occur if the material is not assigned to a supply source or if the supply assignment is not supported for the specific item.
  
  
  Material Master Settings: The material master record may not have the necessary settings for availability checks. This includes settings in the MRP (Material Requirements Planning) views.
