  The SAP error message /SAPCE/IUUA_MES210 Entry with the elementID & already exists in Reactors typically indicates that there is an attempt to create or insert a new entry in the Reactors table (or a similar data structure) with an elementID that already exists. This can happen in various scenarios, such as during data uploads, batch processing, or when manually entering data.
  Cause:
  
  Duplicate Entry: The most common cause is that the elementID you are trying to insert is already present in the database. This could be due to a previous entry that was not deleted or a data import that included duplicates.
  Data Integrity Issues: There may be issues with data integrity, where the system is not correctly validating existing entries before allowing new ones.

  SELECT * FROM Reactors WHERE elementID = 'your_elementID';
  
  Modify the Entry: If the entry already exists and you need to update it, consider using an UPDATE statement instead of an INSERT.
  Delete the Existing Entry: If the existing entry is no longer needed, you can delete it before attempting to insert the new one.
  DELETE FROM Reactors WHERE elementID = 'your_elementID';
  
  Error Handling in Code: If this error is occurring in a custom program or report, ensure that the code includes proper error handling and checks for existing records before attempting to insert new ones.
