  SAP Error Message:
  WG456 PO &1 rejected: supplier sub-range not in selection range
  
  Cause:
  This error occurs when a Purchase Order (PO) is being processed or released, and the supplier (vendor) associated with the PO falls outside the allowed or predefined supplier sub-range for the user or organizational unit performing the action.
  In SAP, supplier sub-ranges are often used to restrict or control which suppliers can be selected or processed by certain users or departments. If the supplier number on the PO is not within the authorized supplier sub-range, the system rejects the PO with this error.
  
  Explanation:
  
  Supplier sub-range: A subset or range of supplier/vendor numbers assigned to a particular user, purchasing group, or organizational unit.
  Selection range: The allowed range of suppliers that a user or process can work with.
  The system checks if the supplier on the PO is within the allowed supplier sub-range.
  If not, the PO is rejected with message WG456.
  
  
  Solution:
  
  
  Check Supplier Sub-Range Assignment:
  
  Verify the supplier number on the PO.
  Check the supplier sub-range assigned to the user or purchasing group.
  Transaction codes to check supplier sub-ranges:
  
  ME01 (Maintain Source List) — sometimes supplier sub-ranges are maintained here.
  ME52N / ME22N — check PO details.
  OMWB — Maintain supplier sub-ranges (depending on configuration).
  
  
  
  
  
  Adjust Supplier Sub-Range:
  
  If the supplier should be allowed, extend the supplier sub-range to include the supplier number.
  This is usually done by the purchasing or system administrator.
  
  
  
  Change User Authorization:
  
  If the user is not authorized for the supplier sub-range, update the user roles/authorizations to include the required supplier sub-range.
  Use transaction PFCG to adjust roles and authorizations.
  
  
  
  Use Correct Supplier:
  
  If the supplier is incorrect, change the PO to use a supplier within the allowed sub-range.
  
  
  
  Check Customizing Settings:
  
  Sometimes, this error is controlled by custom validation or user-exits.
  Check if there are any user-exits or BAdIs that enforce supplier sub-range checks.

  Common Transactions:

  ME22N — Change Purchase Order
  ME52N — Change Purchase Requisition
  PFCG — Role maintenance for authorizations
