XS125 - Details

• 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
