  SAP Error Message:
  
  WR166 - Enter a value for affecting stock
  
  Cause:
  This error occurs when you are performing a goods movement or inventory transaction in SAP (such as a goods receipt, goods issue, transfer posting, or physical inventory) and the system expects a quantity that affects stock, but no such quantity has been entered.
  In other words, the system requires a quantity that will impact the stock levels, but the input field for the quantity affecting stock is either empty or zero.
  
  When does it typically occur?
  
  During goods movement transactions (MIGO, MB1A, MB1B, MB1C, etc.)
  When posting inventory differences
  When entering physical inventory documents
  When transferring stock between storage locations or plants
  When the movement type requires a quantity that affects stock but the quantity field is left blank or zero
  
  
  Solution:
  
  
  Enter a valid quantity:
  
  Make sure to enter a positive or negative quantity (depending on the transaction) in the quantity field that affects stock.
  
  
  Check the movement type:
  
  Verify that the movement type you are using requires a quantity that affects stock. Some movement types may not require quantity input or may have special rules.
  
  
  Check the item category:
  
  Ensure the item category or material type allows stock changes and that the quantity field is enabled.
  
  
  Review the transaction screen:
  
  Sometimes, the quantity field might be hidden or disabled due to screen layout or user exit/customization. Make sure the quantity field is visible and editable.
  
  
  Check for user exits or BAdIs:
  
  Custom code might be enforcing additional validations. Review any user exits or BAdIs related to the transaction for additional checks on quantity.
  
  
  
  Additional Information:
  
  Message Class: WR (Warehouse Management)
