  SAP Error Message: WI703 - Invalid task type
  
  Cause:
  The error WI703 - Invalid task type occurs when the workflow engine encounters a task type that is not recognized or is invalid in the context of the workflow definition or execution. This typically happens due to one of the following reasons:
  
  The task type specified in the workflow definition does not exist or is incorrectly defined.
  The task type is not properly configured or activated in the system.
  There is a mismatch between the task type expected by the workflow and the actual task type assigned.
  The workflow template or task has been modified or corrupted, leading to an invalid task type reference.
  Custom task types are used but not properly registered or implemented.
  
  
  Solution:
  To resolve the WI703 - Invalid task type error, follow these steps:
  
  
  Check the Task Type in the Workflow:
  
  Go to transaction SWDD (Workflow Builder).
  Open the workflow definition where the error occurs.
  Identify the task that triggers the error.
  Verify the task type assigned to this task (e.g., standard task, container task, method task, etc.).
  
  
  
  Verify Task Type Configuration:
  
  For standard tasks, check if the task exists in transaction PFTC (Task Maintenance).
  Ensure the task type is correctly defined and active.
  For custom tasks, ensure that the task type is properly implemented and registered.
  
  
  
  Check for Transport or System Issues:
  
  If the workflow or task was transported from another system, verify that all related objects (tasks, methods, container elements) were transported correctly.
  Sometimes, missing or inconsistent transports cause invalid task types.
  
  
  
  Recreate or Correct the Task:
  
  If the task type is invalid or corrupted, consider recreating the task or correcting the task type in the workflow.
  Replace the invalid task with a valid one.
  
  
  
  Check SAP Notes and Support:
  
  Search for relevant SAP Notes that might address known issues with task types.
  For example, SAP Notes related to workflow or task type inconsistencies.
  
  
  
  Debugging:
  
  If the issue persists, debugging the workflow runtime (using transaction SWUS or SWI1) can help identify where the invalid task type is being called.
