• What is the cause and solution for SAP error message GT818 - Commit after at least every & bytes ?

  The SAP error message GT818 ("Commit after at least every & bytes") typically occurs in the context of data processing, particularly when dealing with large volumes of data in SAP systems. This error is related to the way SAP handles database commits during data operations, such as batch processing or data uploads.
  Cause:
  The error GT818 is triggered when the system attempts to process a large amount of data without committing the changes to the database frequently enough. SAP has a limit on how much data can be processed in a single transaction to ensure data integrity and performance. If the data volume exceeds the specified threshold (the "&" in the message indicates the byte limit), the system raises this error to prevent potential issues such as memory overflow or transaction log overflow.
  Solution:
  To resolve the GT818 error, you can take the following steps:
  
  
  Adjust the Commit Frequency:
  
  Modify the program or process that is generating the error to include more frequent commits. This can be done by breaking down the data processing into smaller chunks and committing after processing each chunk.
  
  
  
  Batch Size Configuration:
  
  If you are using a standard SAP program or transaction, check if there are parameters or settings that allow you to configure the batch size or commit frequency. This may involve adjusting settings in the program or using transaction codes like SE38 to modify the ABAP code.
  
  
  
  Review Data Volume:
  
  Analyze the volume of data being processed. If possible, reduce the amount of data being processed in a single transaction. This can involve filtering the data or processing it in smaller segments.
  
  
  
  Check System Parameters:
  
  Consult with your SAP Basis team to review system parameters related to database transactions and memory management. They may be able to adjust settings that could help alleviate the issue.
  
  
  
  Error Handling:
  
  Implement error handling in your ABAP code to catch this error and handle it gracefully, possibly by retrying the operation with a smaller data set.
  
  
  
  Related Information:
  
  Transaction Logs: Frequent commits help manage transaction logs effectively, preventing them from growing too large and causing performance issues.
  Performance Considerations: While committing frequently can help avoid the GT818 error, it may also impact performance. It's essential to find a balance between commit frequency and overall processing time.
  SAP Notes: Check SAP Notes for any specific recommendations or patches related to this error. SAP frequently updates its knowledge base with solutions for common issues.
  
  If the problem persists after trying the above solutions, it may be beneficial to consult with SAP support or your internal SAP technical team for further assistance.
