  Error Message
  W_CB129: Enter a purchase order number for item &1
  
  Message Class: CB1 (related to Inventory Management / Goods Movement)
  Type: Warning (W)
  
  
  Cause
  This warning occurs during a goods movement or goods receipt transaction when the system expects a purchase order (PO) number to be entered for a particular item but it is missing.
  Typically, this happens in scenarios such as:
  
  When posting a goods receipt against a purchase order, the system requires the PO number to link the receipt to the correct order.
  The item in the document is configured or expected to be linked to a PO, but the PO number field is left blank.
  The movement type or transaction requires a PO reference for the item, but it was not provided.
  
  
  Explanation
  SAP uses the purchase order number to:
  
  Ensure the goods receipt is correctly matched to the purchase order.
  Update the PO history and monitor open quantities.
  Facilitate invoice verification and payment processing.
  
  If the PO number is missing, the system cannot perform these checks properly, hence the warning.
  
  Solution
  
  
  Enter the Purchase Order Number:
  
  When prompted, input the correct purchase order number for the item.
  Make sure the PO number corresponds to the item being posted.
  
  
  
  Check the Movement Type:
  
  Verify if the movement type used requires a PO reference.
  For example, movement types like 101 (Goods receipt for purchase order) require a PO number.
  
  
  
  Verify Item Data:
  
  Confirm that the item is indeed linked to a PO.
  If the item is not supposed to be linked to a PO, check if the configuration or master data is correct.
  
  
  
  Check Document Entry Screen:
  
  In the goods movement screen (e.g., MIGO), ensure the PO number is entered in the relevant field for the item.
  
  
  
  Consult with Purchasing Department:
  
  If unsure about the PO number, coordinate with purchasing to get the correct PO.
  
  
  
  
  Additional Information
  
  This is a warning message, so the system may allow you to continue posting, but it is recommended to enter the PO number to maintain data integrity.
  If you want to suppress this warning (not recommended), you can check the message control settings in transaction OMJJ or related configuration, but this should be done only if business processes allow it.
  The message variable &1 will be replaced by the item number in the actual message, indicating for which item the PO number is missing.
