• What is the cause and solution for SAP error message GT235 - Number of eliminated duplicates = & ?

  The SAP error message GT235, which states "Number of eliminated duplicates = &", typically occurs in the context of data processing, particularly when dealing with internal tables or data sets in ABAP programs. This message indicates that during a certain operation (like a SELECT statement or data manipulation), SAP has identified and removed duplicate entries from a dataset.
  Cause:
  
  Duplicate Data: The primary cause of this message is the presence of duplicate entries in the data being processed. This can happen when data is fetched from a database table that contains duplicate records based on the criteria used in the query.
  Data Processing Logic: The logic in the ABAP program may not be correctly handling duplicates, leading to the elimination of records that may be needed.
  Incorrect Use of SELECT DISTINCT: If a SELECT statement is used with the DISTINCT keyword, it will automatically eliminate duplicates, which can trigger this message.
  
  Solution:
  
  Review Data Source: Check the underlying database table for duplicate records. You can run a query to identify duplicates based on the relevant fields.
  Adjust ABAP Logic: If the duplicates are valid and should not be eliminated, review the ABAP code to ensure that the logic is correctly handling duplicates. You may need to adjust the SELECT statement or the way data is processed.
  Use GROUP BY: If you need to aggregate data instead of eliminating duplicates, consider using a GROUP BY clause in your SQL query to summarize the data appropriately.
  Data Cleansing: If duplicates are not supposed to exist, consider implementing data cleansing processes to remove or merge duplicate records in the database.
  Debugging: Use debugging tools in SAP to trace the execution of the program and see where duplicates are being eliminated. This can help identify the root cause.
