  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WG455 PO &1 rejected: supplier material no. not in selection range
  
  Meaning / Cause:
  This error occurs during the processing of a Purchase Order (PO) when the supplier material number (also called the vendor material number or external material number) assigned to a PO item is not within the allowed or defined selection range in the system.
  In other words, the system checks the supplier material number against a predefined range or list of valid supplier material numbers (usually maintained in the material master or vendor master data). If the supplier material number on the PO item falls outside this range or is not recognized, the system rejects the PO with this message.
  This typically happens in scenarios where:
  
  The supplier material number is maintained with a range restriction in the system.
  The supplier material number is missing or incorrectly entered.
  The system is configured to validate supplier material numbers against a selection range or allowed list.
  Custom validations or user-exits/BAdIs are implemented to enforce supplier material number ranges.
  
  
  Where is this check done?
  
  The check is often done in the material master (MARA, MARC tables) or vendor master (LFA1, LFM1) where supplier material numbers are maintained.
  It can also be part of custom validations in user-exits or BAdIs related to purchasing documents.
  Sometimes, the check is linked to info records (ME11/ME12) where supplier material numbers are maintained and validated.
  
  
  Solution / How to fix:
  
  
  Verify Supplier Material Number:
  
  Check the supplier material number entered in the PO item.
  Ensure it is correct and matches the supplier's actual material number.
  
  
  
  Check Material Master / Vendor Master:
  
  Go to transaction MM03 (Display Material) and check the supplier material number(s) maintained under the Purchasing view or Vendor-specific material number.
  Alternatively, check the vendor master or info record for the supplier material number.
  
  
  
  Maintain or Correct Supplier Material Number:
  
  If missing, maintain the correct supplier material number in the material master or info record using ME11/ME12.
  If the supplier material number is outside the allowed range, adjust the range or add the number to the allowed list.
  
  
  
  Check Custom Validations:
  
  If your system has custom validations (user-exits, BAdIs) that restrict supplier material numbers, review and adjust the logic accordingly.
  Common user-exits related to PO processing include EXIT_SAPMM06E_012 or BAdIs like ME_PROCESS_PO_CUST.
  
  
  
  Adjust Selection Range:
  
  If the system uses a selection range or interval table for supplier material numbers, update the range to include the required supplier material number.
  
  
  
  Reprocess the PO:
  
  After corrections, try to save or process the PO again.
