  Message Text:
  
  Entry in material master for material & and plant &
  
  Cause
  This warning message appears when you are trying to create or change a material master record for a specific material and plant, but the system detects that an entry for this material and plant combination already exists in the material master.
  In other words, the system is informing you that the material master data for the given material number and plant is already present, so creating a duplicate entry is not allowed.
  
  When does it occur?
  
  When you attempt to create a material master record in transaction MM01 or change it in MM02, and the system finds that the material-plant combination already exists.
  During data upload or batch input sessions where material master data is being created.
  When customizing or master data maintenance programs try to insert duplicate entries.
  
  
  Solution
  
  
  Check if the material master record for the given material and plant already exists:
  
  Use transaction MM03 (Display Material) and enter the material and plant to verify the existing data.
  
  
  If you want to change the existing data:
  
  Use MM02 to modify the material master record instead of creating a new one.
  
  
  If you intended to create a new material:
  
  Use a different material number that does not exist in the system.
  
  
  If this occurs during data upload:
  
  Review the upload file to ensure no duplicate entries for the same material and plant combination are present.
  
  
  If you want to add data for a new plant:
  
  You can extend the material to the new plant using MM01 and selecting the option to extend the material to additional plants.
