  The SAP error message SWDP_WB_TOOL118, which states "Event parameters have been matched," typically occurs in the context of SAP Web Dynpro applications. This error is related to the event handling mechanism in Web Dynpro, where the parameters expected by an event do not match the parameters that are actually provided.
  Cause:
  
  
  Parameter Mismatch: The most common cause of this error is that the event parameters defined in the Web Dynpro component do not match the parameters being passed during the event triggering. This can happen if:
  
  The event is triggered with incorrect or missing parameters.
  The data types of the parameters do not match.

  Configuration Issues: There may be issues in the configuration of the Web Dynpro component or the view that is causing the parameters to not align correctly.
  
  
  Coding Errors: If there are custom implementations or modifications in the event handling logic, coding errors could lead to this mismatch.

  Check Event Definitions: Review the event definitions in the Web Dynpro component. Ensure that the parameters defined for the event match the parameters being passed when the event is triggered.
  
  
  Parameter Types: Verify that the data types of the parameters match. For example, if an event expects a string, ensure that a string is being passed and not an integer or another type.
  
  
  Debugging: Use the debugging tools in SAP to trace the event handling process. Check the values of the parameters being passed at runtime to identify any discrepancies.
  
  
  Review Custom Code: If there is custom code involved in the event handling, review it for any logical errors that might be causing the mismatch.
  
  
  Testing: After making changes, thoroughly test the application to ensure that the event handling works as expected without triggering the error.
