  Error Message
  WZ507: The passed event parameters have errors
  
  Cause
  This error occurs in SAP Workflow when the event parameters passed to a workflow container or a workflow step are incorrect or inconsistent. Specifically:
  
  The parameters passed to the workflow event do not match the expected data types or structures defined in the event.
  Mandatory parameters are missing.
  The parameters are passed in the wrong sequence or with incorrect values.
  The event triggering the workflow is called with incorrect or incomplete data.
  
  In other words, the workflow runtime detects that the event parameters it received are not valid according to the event definition.
  
  When does it occur?
  
  When triggering a workflow event using function modules like SAP_WAPI_EVENT_RAISE or SAP_WAPI_EVENT_RAISE_MAINT.
  When a workflow step is triggered and the container binding fails due to parameter mismatch.
  During event raising in custom workflows or standard workflows with custom enhancements.
  
  
  Solution
  
  
  Check Event Definition:
  
  Go to transaction SWETYPV (Event Type Linkage) or SWO1 (Business Object Builder).
  Verify the event parameters defined for the event that is being raised.
  Confirm the data types, parameter names, and mandatory parameters.
  
  
  
  Check Event Raising Code:
  
  If the event is raised via ABAP code (e.g., SAP_WAPI_EVENT_RAISE), check the parameters passed.
  Ensure the parameters match exactly the event definition in type and sequence.
  Example:
  CALL FUNCTION 'SAP_WAPI_EVENT_RAISE'
    EXPORTING
      event_object = 'BUS2032'
      event_id     = 'CREATED'
      event_container = lt_container
    EXCEPTIONS
      error_in_event_parameters = 1
      OTHERS = 2.
  
  Make sure lt_container contains all required parameters with correct types.
  
  
  
  Check Workflow Container Bindings:
  
  In transaction PFTC or SWDD (Workflow Builder), check the container binding of the workflow step.
  Ensure the container elements are correctly mapped to the event parameters.
  
  
  
  Debugging:
  
  Use the debugger to check the content of the container or parameters passed during event raising.
  Check for missing or wrongly typed parameters.
  
  
  
  Correct Data Types and Values:
  
  Make sure that the parameters passed are not only present but also valid (e.g., correct object keys, valid structures).
  
  
  
  Re-generate or Adjust Event Parameters:
  
  If the event parameters have been changed recently, regenerate or adjust the workflow container accordingly.
  
  
  
  
  Related Information
  
  
  Transactions:
  
  SWO1 - Business Object Builder (to check event and parameters)
  SWETYPV - Event Type Linkage (to check event linkage)
  SWDD - Workflow Builder (to check workflow container and steps)
  PFTC - Task Maintenance (to check task container)
  
  
  
  Function Modules:
  
  SAP_WAPI_EVENT_RAISE - Raises an event in workflow
  SAP_WAPI_EVENT_RAISE_MAINT - Raises an event with container parameters

  Common Scenarios:
  
  Custom workflows where event parameters are manually passed.
  Standard workflows enhanced with custom events or parameters.
