  SAP Error Message:
  
  WSTP000 - Enter a material or EAN/UPC
  
  Cause:
  This error message appears when the system expects the user to enter either a Material Number or an EAN/UPC (European Article Number / Universal Product Code), but neither has been provided. It typically occurs in transactions or screens where the system requires identification of a product, such as in goods movement, sales order entry, inventory management, or point-of-sale scenarios.
  
  When does it occur?
  
  When creating or processing documents that require a material or barcode input.
  During scanning or manual entry in logistics or sales transactions.
  In custom programs or standard SAP transactions where material identification is mandatory.
  
  
  Solution:
  
  Enter a valid Material Number: Input the correct material number in the designated field.
  Enter a valid EAN/UPC: If the system supports barcode scanning or entry, provide the correct EAN/UPC code.
  Check input fields: Ensure that the fields for material or EAN/UPC are not left blank.
  Verify master data: Confirm that the material or EAN/UPC exists in the material master (MM03) and is active.
  Check configuration: If the system expects EAN/UPC but you only have material numbers, verify if the system configuration or user exit requires EAN/UPC input.
  User training: Make sure users understand which field to fill and the format expected.
  
  
  Related Information:

  Debugging: If the error appears unexpectedly, check user exits or enhancements that might enforce this validation.
  
  
  Summary:
  The error WSTP000 is a prompt to ensure that either a material number or an EAN/UPC code is entered to identify the product. Providing the required input resolves the error. If the error persists despite correct input, investigate master data and system configuration.
