• What is the cause and solution for SAP error message SADL_GW026 - Sticky session request error: Save and Discard session in same batch ?

  The SAP error message SADL_GW026 indicates a "Sticky session request error," specifically stating that a "Save and Discard session in the same batch" has occurred. This error typically arises in the context of the SAP Gateway and the SAP Application Development Layer (SADL) when there is an issue with how session management is being handled during a batch operation.
  Cause:
  The error occurs when a request attempts to perform both a "Save" and a "Discard" operation within the same session or batch. This is not allowed because it creates ambiguity in the session state. The system cannot determine whether to commit the changes (Save) or to discard them, leading to a conflict.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the Code Logic: Check the logic in your application or service that is generating the requests. Ensure that you are not trying to save and discard changes in the same batch operation. Separate these operations into distinct requests.
  
  
  Session Management: Ensure that your session management is correctly implemented. If you need to perform multiple operations, consider using separate sessions for each operation or ensure that the operations are logically sequenced.
  
  
  Error Handling: Implement proper error handling in your application to catch such scenarios and provide meaningful feedback to the user or system.
  
  
  Testing: After making changes, thoroughly test the application to ensure that the error does not occur again and that the intended functionality works as expected.
  
  
  Consult Documentation: Refer to the SAP documentation for SADL and the SAP Gateway for any specific guidelines or best practices related to session management and batch processing.
  
  
  SAP Support: If the issue persists after trying the above solutions, consider reaching out to SAP support for further assistance. They may provide insights specific to your implementation or version.
