• What is the cause and solution for SAP error message /PLMI/BO_MPN101 - List contains entries for blocked manufacturers ?

  The SAP error message /PLMI/BO_MPN101 List contains entries for blocked manufacturers typically occurs in the context of managing materials and manufacturers in the SAP system, particularly when dealing with the Manufacturer Part Number (MPN) functionality. This error indicates that there are entries in the list that refer to manufacturers that have been blocked in the system, which means that you cannot use these manufacturers for procurement or other processes.
  Cause:
  
  
  Blocked Manufacturers: The primary cause of this error is that the manufacturer(s) associated with the materials you are trying to process are marked as blocked in the system. This could be due to various reasons, such as:
  
  The manufacturer has been flagged for quality issues.
  The manufacturer is no longer in business.
  The manufacturer has been temporarily blocked for other operational reasons.
  
  
  
  Data Integrity Issues: There may be inconsistencies in the data where the system is trying to reference a manufacturer that is not active or has been marked as blocked.
  
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Manufacturer Status:
  
  Go to the relevant transaction (e.g., MM03 for material master or BP for business partner) and check the status of the manufacturer in question.
  If the manufacturer is indeed blocked, you will need to determine if it should be unblocked or if you need to find an alternative manufacturer.
  
  
  
  Unblock Manufacturer:
  
  If the manufacturer should be active, you can unblock it by navigating to the appropriate transaction (e.g., BP for business partner) and changing the status from blocked to active.
  Ensure that you have the necessary authorizations to make this change.
  
  
  
  Update Material Master:
  
  If you have materials linked to the blocked manufacturer, you may need to update the material master records to either remove the association with the blocked manufacturer or replace it with an active one.
  
  
  
  Consult with Relevant Departments:
  
  If you are unsure about the status of the manufacturer or the implications of unblocking it, consult with your procurement, quality assurance, or compliance departments to ensure that you are making the right decision.
  
  
  
  Review Customizations:
  
  If your organization has custom developments or enhancements related to manufacturer management, review those to ensure they are not causing the issue.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MM03 (Display Material), MM02 (Change Material), BP (Business Partner), and ME11 (Create Purchasing Info Record).
  Authorization: Ensure you have the necessary authorizations to view and modify manufacturer and material data.
  Documentation: Refer to SAP documentation or your organization's internal guidelines for managing blocked manufacturers and the implications of unblocking them.
  
  By following these steps, you should be able to resolve the error and continue with your processes in SAP.
