• What is the cause and solution for SAP error message WP507 - Both EAN & and material & unknown ?

  SAP Error Message:
  
  WP507 – "Both EAN & & material & unknown"
  
  Cause:
  This error occurs when the system cannot find a valid match for the combination of the EAN (European Article Number) and the material number provided during a process (such as goods receipt, goods issue, or sales order processing). Essentially, the system is trying to identify a material based on the EAN code, but either:
  
  The EAN code is not assigned to the material in the system, or  
  The material number entered does not exist or is not linked to the EAN code, or  
  The EAN code is unknown or missing in the material master data.
  
  
  Explanation:
  
  EAN (European Article Number) is a barcode standard used to uniquely identify products.
  In SAP, materials can have multiple EANs assigned in the material master (usually in the Additional Data tab or via transaction MM02 under the EAN/UPC codes).
  When scanning or entering an EAN, SAP tries to find the corresponding material.
  If the system cannot find a material linked to the EAN or the material number is incorrect, it throws this error.
  
  
  Solution:
  
  
  Check EAN assignment to material:
  
  Go to transaction MM03 (Display Material).
  Enter the material number.
  Navigate to the Additional Data tab ? EAN/UPC Codes.
  Verify if the EAN code in question is assigned to the material.
  If not assigned, use MM02 to add the correct EAN code to the material master.
  
  
  
  Verify the material number:
  
  Ensure the material number entered is correct and exists in the system.
  Use MM03 to check if the material is active and valid.
  
  
  
  Check for correct EAN input:
  
  Confirm that the EAN code scanned or entered is correct and complete.
  Sometimes scanning errors or incomplete EANs cause this issue.
  
  
  
  Update or maintain EAN master data:
  
  If the EAN is new, it must be created and linked to the material.
  Use transaction MM02 to maintain EAN codes.
  
  
  
  Check configuration if applicable:
  
  In some cases, the system might be configured to require EAN validation.
  Check if any custom validation or user-exits are causing the issue.
  
  
  
  
  Related Information:
  
  
  Transaction codes:  
  
  MM03 – Display Material  
  MM02 – Change Material  
  MM01 – Create Material (if material does not exist)  
  
  
  
  Tables involved:  
  
  MARA – General Material Data  
  MARC – Plant Data for Material  
  MARM – Units of Measure for Material  
  EAN/UPC codes are stored in MARM or related tables depending on SAP version.
  
  
  
  Notes:  
  
  Ensure barcode scanners are configured correctly if scanning EANs.  
  If using batch or serial numbers, verify their linkage to materials and EANs.
  
  
  
  
  Summary:
  The error WP507 indicates a mismatch or missing link between the EAN code and the material number in SAP. The solution is to verify and maintain the correct EAN assignments in the material master and ensure the material number is valid and active.
  
  If you need further assistance, please provide the exact transaction or process where the error occurs, and the EAN and material numbers involved.
