  Check Event Triggers: Review the event triggers in your application to ensure that actions are not being called multiple times unnecessarily. This may involve checking button clicks, form submissions, or other user interactions.
  Implement State Checks: Before executing an action, implement checks to determine if the action has already been executed. This can be done using flags or state variables.
  Debugging: Use debugging tools to trace the execution flow of your application. This can help identify where the duplicate execution is occurring.
  Review Action Logic: Ensure that the logic within the actions or expressions is designed to handle multiple calls gracefully, if necessary.
  Consult Documentation: Refer to SAP documentation or community forums for specific guidance related to the version of SAP you are using, as there may be version-specific nuances.
