M3220 - Details

• The SAP error message M3220, which states "Master record already exists," typically occurs when you attempt to create a new master record (such as a material master, vendor master, or customer master) that already exists in the system. This can happen in various modules, including Materials Management (MM) and Sales and Distribution (SD).
  
  Cause:
  
  Duplicate Entry: The most common cause is that the master record you are trying to create already exists in the database. This could be due to a previous entry that was not properly identified or due to an attempt to create a record with the same key fields (like material number, vendor number, etc.).
  Incorrect Data Entry: Sometimes, the data you are entering may not be unique, or you may have mistakenly entered the same data as an existing record.
  Data Migration Issues: If data was migrated from another system, there may be duplicates that were not cleaned up before
