  Stock Availability: The stock levels may not meet the requirements for the requested quantity, or there may be issues with stock transfers or reservations.
  
  
  Integration Issues: Problems with the integration between SAP ERP and SAP APO can lead to ATP errors, especially if the systems are not synchronized properly.
