• What is the cause and solution for SAP error message MFLE_TOOLS152 - MATNR_EXT &1 in client &2 is a duplicate to MATNR_EXT_TEMP. ?

  The SAP error message MFLE_TOOLS152 indicates that there is a duplicate entry for a material number (MATNR_EXT) in the specified client. This typically occurs during the process of importing or creating material master data, where the system detects that the material number you are trying to create or modify already exists in a temporary table (MATNR_EXT_TEMP).
  Cause:
  
  Duplicate Material Number: The primary cause of this error is that the material number you are trying to create or import already exists in the system or in a temporary table.
  Data Import Issues: If you are importing data from an external source, there may be duplicates in the source data.
  Incorrect Data Handling: During data migration or updates, if the same material number is processed multiple times without proper checks, it can lead to this error.
  
  Solution:
  
  
  Check for Existing Material: Verify if the material number already exists in the system. You can do this by using transaction codes like MM03 (Display Material) or MM02 (Change Material) to see if the material number is already in use.
  
  
  Review Temporary Table: Check the contents of the temporary table (MATNR_EXT_TEMP) to see if the material number is listed there. You can use transaction SE16 or SE11 to view the contents of the table.
  
  
  Remove Duplicates: If you find that the material number exists in the temporary table and is not needed, you can delete the duplicate entry from the temporary table. Be cautious when doing this to avoid data integrity issues.
  
  
  Data Cleansing: If you are importing data, ensure that your source data is cleansed and does not contain duplicates before the import process.
  
  
  Error Handling in Data Migration: If this error occurs during a data migration process, implement error handling to catch duplicates and handle them appropriately, either by skipping them or updating existing records.
  
  
  Consult Documentation: Refer to SAP documentation or support for specific guidelines related to your version of SAP, as there may be additional considerations based on your system configuration.
