• What is the cause and solution for SAP error message MPN01010 - MPN & is not unique (add manufacturer) ?

  The SAP error message MPN01010 indicates that the Manufacturer Part Number (MPN) you are trying to use is not unique in the system. This typically occurs when you attempt to create or update a material with a manufacturer part number that already exists in the database, but it is associated with a different manufacturer or material.
  Cause:
  
  Duplicate MPN: The MPN you are trying to enter is already associated with another material or manufacturer in the system.
  Incorrect Manufacturer Assignment: The MPN might be linked to a different manufacturer than the one you are trying to associate it with.
  Data Entry Error: There may be a typographical error in the MPN or manufacturer details.
  
  Solution:
  
  Check Existing MPNs: Use transaction codes like MM03 (Display Material) or MM02 (Change Material) to check if the MPN already exists in the system. Look for the MPN in the relevant material master records.
  Verify Manufacturer: Ensure that the MPN you are trying to add is indeed associated with the correct manufacturer. If it is not, you may need to add the manufacturer to the existing MPN or create a new MPN for the new manufacturer.
  Create a New MPN: If the MPN is already in use and you need to associate it with a different manufacturer, consider creating a new MPN that is unique to that manufacturer.
  Data Cleanup: If there are duplicates that should not exist, you may need to clean up the data by removing or merging duplicate entries, but this should be done with caution and typically requires appropriate authorizations.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MM01 (Create Material), MM02 (Change Material), and MM03 (Display Material) to manage material master data.
