• What is the cause and solution for SAP error message /BEV4/PLPEND037 - External material number already assigned to internal material number: &1 ?

  The SAP error message /BEV4/PLPEND037 indicates that an external material number you are trying to assign is already linked to an internal material number in the system. This typically occurs in scenarios where you are working with material master data, especially in the context of logistics or inventory management.
  Cause:
  
  Duplicate Assignment: The external material number you are trying to use is already assigned to another internal material number. This can happen if the same external number is being used for different materials.
  Data Migration Issues: If you are migrating data from another system or performing a mass upload, there may be conflicts with existing data.
  Incorrect Configuration: The system may be configured in a way that does not allow for the reuse of external material numbers.
  
  Solution:
  
  
  Check Existing Assignments: Use transaction codes like MM03 (Display Material) or MM02 (Change Material) to check if the external material number is already assigned to an internal material number. You can also use the transaction SE16N to query the relevant tables (e.g., MARA, MARC) to find existing assignments.
  
  
  Use a Different External Number: If the external material number is already in use, consider using a different external number that is not currently assigned.
  
  
  Unassign the Existing Number: If the existing assignment is no longer needed, you may consider unassigning the external material number from the internal material number. This should be done with caution and typically requires appropriate authorization.
  
  
  Data Cleanup: If this issue arises from data migration, ensure that the data being imported does not contain duplicates. Clean up the data before attempting to import it again.
  
  
  Consult Documentation: Review SAP documentation or consult with your SAP administrator for specific configurations related to material number assignments.
  
  
  Related Information:
  
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MM01 (Create Material), MM02 (Change Material), and MM03 (Display Material).
  
  
  Tables: Understand the relevant tables involved in material master data, such as:
  
  MARA (General Material Data)
  MARC (Plant Data for Material)
  MAST (Material to BOM Link)
  
  
  
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
