  Error Message
  WP601: Several open POs found for GR: material &, plant &
  
  Cause
  This error occurs during the Goods Receipt (GR) process when the system tries to post a goods receipt for a material and plant combination, but finds multiple open Purchase Orders (POs) for the same material and plant. The system cannot determine unambiguously which PO the goods receipt should be posted against.
  In other words, the system expects a single open PO for the material and plant, but multiple POs are open, causing ambiguity.
  
  When does it occur?
  
  During Goods Receipt (MIGO) or Inbound Delivery processing.
  When the system tries to automatically assign the PO for the GR but finds more than one open PO for the same material and plant.
  Typically happens if multiple POs exist for the same material and plant, and the user or system does not specify the PO number explicitly.
  
  
  Solution
  
  
  Specify the PO number explicitly:
  
  When posting the goods receipt, enter the exact PO number to which the GR should be posted.
  This removes ambiguity and directs the system to the correct PO.
  
  
  
  Check open POs for the material and plant:
  
  Use transaction ME2M or ME2L to list all open POs for the material and plant.
  Identify which PO the goods receipt should be posted against.
  
  
  
  Close or complete unnecessary POs:
  
  If some POs are no longer valid or should not receive goods, consider closing or completing them to avoid confusion.
  
  
  
  Use delivery note or inbound delivery reference:
  
  If inbound delivery is used, ensure the delivery document is referenced correctly to link the GR to the correct PO.
  
  
  
  Check configuration for GR processing:
  
  Sometimes, custom enhancements or user exits may cause this issue if they do not handle multiple POs properly.
  
  
  
  
  Additional Information
  
  This message is a safeguard to prevent incorrect posting of goods receipts to the wrong PO.
  It is important to maintain clear and unambiguous PO and GR processes.
  If multiple POs for the same material and plant are common in your process, consider process changes or system enhancements to handle this scenario better.
  The message text can be found in transaction SE91 by entering message class WP6 and message number 01.
