  Error Message
  WSTP002: Several materials are assigned to EAN/UPC &1
  
  Cause
  This error occurs when the system detects that a single EAN/UPC code (European Article Number / Universal Product Code) is assigned to multiple materials in the SAP system. In SAP, an EAN/UPC code is expected to uniquely identify a material. If the same barcode is linked to more than one material master record, the system cannot determine which material to use, leading to this error.
  
  Explanation
  
  EAN/UPC codes are used for product identification and scanning in logistics, sales, and inventory processes.
  Each EAN/UPC should be unique to a material to avoid confusion.
  When multiple materials share the same EAN/UPC, processes like goods movement, sales order processing, or barcode scanning fail because the system cannot resolve the ambiguity.
  
  
  Solution
  
  
  Identify the materials assigned to the EAN/UPC code:
  
  Use transaction MMBE (Stock Overview) or MM03 (Display Material) to check the EAN/UPC assignments.
  Alternatively, use table MARA or EANLH (EAN/UPC code table) to find all materials linked to the problematic EAN/UPC.
  
  
  
  Correct the EAN/UPC assignments:
  
  Determine which material should have the EAN/UPC code.
  Remove or change the EAN/UPC code from the other materials.
  This can be done in transaction MM02 (Change Material) under the Basic Data 1 or Additional Data tab where barcodes are maintained.
  
  
  
  If multiple materials legitimately share the same EAN/UPC:
  
  This is generally not recommended.
  Consider creating unique EAN/UPC codes for each material.
  If the business process requires shared codes, consult with your SAP functional consultant to explore custom solutions or enhancements.
  
  
  
  Check for data inconsistencies:
  
  Sometimes, data migration or manual entry errors cause duplicates.
  Clean up the master data to maintain data integrity.

  Notes:
  
  Always ensure EAN/UPC codes are unique per material to avoid operational issues.
  Regular master data audits can prevent such errors.
  If using batch management or variant materials, ensure EAN/UPC codes are assigned correctly at the appropriate level.
