MFLE_TOOLS025 - Details

• The SAP error message MFLE_TOOLS025 indicates that there is a duplicate material number (MATNR_LONG) for a material number (MATNR_INT) in a specific client. This typically occurs during the material master data creation or migration process, where the system detects that the long material number you are trying to create already exists in the system for the specified client.
  
  Cause:
  
  Duplicate Material Numbers: The long material number you are trying to create already exists in the system, which violates the uniqueness constraint for material numbers.
  Data Migration Issues: If you are migrating data from another system or performing a mass upload, there may be duplicates in the source data.
  Incorrect Configuration: The configuration settings for material number assignment may not be set up correctly, leading to conflicts.
  
  
  Solution:
  
  
  Check Existing Material Numbers: 
  
  Use transaction codes like MM03 (Display Material) or MM02 (Change Material) to check if the long material number already exists in the system.
