• What is the cause and solution for SAP error message XS125 - Only one server group can be selected within a transaction ?

  The SAP error message XS125, which states "Only one server group can be selected within a transaction," typically occurs in the context of SAP HANA or XS (Extended Services) when there is an attempt to perform operations that involve multiple server groups within a single transaction. This is not allowed because transactions must be consistent and isolated, and allowing multiple server groups could lead to inconsistencies.
  Cause:
  
  Multiple Server Groups: The error is triggered when a transaction attempts to access or modify data across different server groups. In SAP HANA, server groups are used to manage resources and distribute workloads, and transactions are designed to operate within a single server group to maintain data integrity.
  Incorrect Configuration: The application or service may be incorrectly configured to access multiple server groups simultaneously.
  Code Logic: The logic in the application code may inadvertently be trying to perform operations across different server groups.
  
  Solution:
  
  Single Server Group Transactions: Ensure that all operations within a transaction are directed to a single server group. Review the transaction logic to confirm that it does not attempt to access multiple server groups.
  Refactor Code: If the application logic requires accessing multiple server groups, consider refactoring the code to separate the operations into different transactions, each targeting a single server group.
  Check Configuration: Review the configuration settings of your SAP HANA system and the application to ensure that they are set up correctly to avoid cross-server group transactions.
  Error Handling: Implement error handling in your application to catch this specific error and provide meaningful feedback to users or logs for debugging.

  By ensuring that your transactions are confined to a single server group, you can avoid encountering the XS125 error in your SAP HANA applications.
