• What is the cause and solution for SAP error message RFM_ST_PICK_REQ021 - Quantity cannot be reduced for item &2 in sales order &1 ?

  The SAP error message RFM_ST_PICK_REQ021 indicates that there is an issue with the quantity of an item in a sales order. Specifically, it means that the quantity for the item (identified by &2) in the sales order (identified by &1) cannot be reduced. This typically occurs during the picking process in the warehouse management or sales order fulfillment process.
  Causes:
  
  Quantity Already Picked: The quantity you are trying to reduce may have already been picked or confirmed in the system, making it impossible to change.
  Delivery Status: The sales order may be linked to a delivery that has already been created, and the delivery quantity cannot be altered.
  Stock Availability: There may be stock constraints or restrictions that prevent the reduction of the quantity.
  Order Type Restrictions: Certain sales order types may have restrictions on quantity changes after certain processes have been initiated.
  Custom Logic: There may be custom logic or user exits in place that enforce specific rules regarding quantity changes.
  
  Solutions:
  
  Check Picking Status: Verify if the item has already been picked. If it has, you may need to reverse the picking or adjust the delivery.
  Review Delivery Document: If a delivery has been created, check the delivery document to see if the quantity can be adjusted there instead.
  Adjust Sales Order: If the sales order is still open and no picking has occurred, you may be able to adjust the quantity directly in the sales order.
  Consult with Warehouse Management: If you are using SAP WM or EWM, consult with the warehouse team to understand the implications of changing the quantity.
  Check for Custom Logic: If there are custom developments in your SAP system, consult with your ABAP team or SAP support to understand any restrictions that may be in place.
