  SAP Error Message:
  WRF_AT108 Quantity of a DC delivery phase was to be < 0; it will be set to 0
  
  
  Cause:
  This warning message occurs during the processing of a Delivery Creation (DC) or during the delivery phase determination in SAP's Sales and Distribution (SD) or Warehouse Management (WM) modules.

  Over-delivery or returns processing where the system tries to adjust quantities.
  Custom enhancements or user exits that manipulate delivery quantities incorrectly.
  Issues in the determination of delivery phases or splitting of quantities across phases.
  Stock inconsistencies or incorrect reservation/deallocation in the warehouse.
