• What is the cause and solution for SAP error message MH151 - EAN & is assigned to suppliers and may not be deleted ?

  The SAP error message MH151 indicates that a specific EAN (European Article Number) is assigned to suppliers and cannot be deleted. This error typically arises in the context of managing material master data, particularly when dealing with product identifiers like EANs.
  Cause:
  The error occurs because the EAN you are trying to delete is currently linked to one or more suppliers in the system. SAP enforces this restriction to maintain data integrity and ensure that all references to the EAN are properly managed.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Assignments: Verify which suppliers are currently assigned to the EAN. You can do this by navigating to the material master data and checking the relevant views (e.g., Purchasing or Sales).
  
  
  Remove Assignments: If you need to delete the EAN, you must first remove its assignment from all suppliers. This can typically be done in the material master record:
  
  Go to the material master transaction (MM02).
  Select the relevant views (e.g., Purchasing).
  Remove the EAN from the supplier assignments.
  
  
  
  Delete EAN: Once the EAN is no longer assigned to any suppliers, you can proceed to delete it.
  
  
  Check for Other Dependencies: Ensure that there are no other dependencies or references to the EAN in other areas of the system that might prevent deletion.
  
  
  Consult Documentation: If you are unsure about the process or need further assistance, refer to SAP documentation or consult with your SAP support team.
  
  
  Related Information:
  
  Material Master Data: Understanding how material master data is structured in SAP can help you navigate and manage EANs effectively.
  Data Integrity: SAP maintains strict data integrity rules, which is why certain actions (like deleting an EAN) are restricted when there are existing references.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MM01 (Create Material), MM02 (Change Material), and MM03 (Display Material) for managing material data.
  
  If you continue to face issues or if the EAN is still not deletable after following these steps, it may be necessary to consult with your SAP administrator or support team for further investigation.
