• What is the cause and solution for SAP error message WI723 - Enter a single-step task (T or TS) ?

  Certainly! Here's a detailed explanation for the SAP error message WI723: Enter a single-step task (T or TS):
  
  SAP Error Message: WI723
  Message Text: Enter a single-step task (T or TS)
  
  Cause:
  This error occurs when you are trying to create or process a workflow step that requires a single-step task, but the task you have entered or selected is not a single-step task. In SAP Workflow, tasks can be either:
  
  Single-step tasks (T or TS): Tasks that represent a single activity or step.
  Multi-step tasks (M or MS): Tasks that consist of multiple steps or activities.
  
  The workflow engine expects a single-step task in this context, but the task provided is either missing, incorrect, or is a multi-step task.
  
  When does this happen?
  
  When defining or modifying a workflow step that requires a single-step task.
  When assigning a task to a workflow step, but the task type is not single-step.
  When importing or copying workflows and the task types do not match the expected type.
  
  
  Solution:
  
  
  Check the Task Type:
  
  Go to transaction PFTC (Task Maintenance).
  Look up the task you are trying to assign.
  Verify if the task is a single-step task (Task type = T or TS).
  
  
  
  Use the Correct Task Type:
  
  If the task is multi-step (M or MS), you need to replace it with a single-step task.
  If you intended to use a multi-step task, adjust the workflow step accordingly or redesign the workflow step to accept multi-step tasks.
  
  
  
  Create a Single-Step Task if Needed:
  
  If no suitable single-step task exists, create a new single-step task in PFTC.
  Assign the appropriate method or activity to this task.
  
  
  
  Adjust Workflow Step:
  
  In the workflow builder (transaction SWDD), ensure that the step is configured to accept a single-step task.
  Replace the task in the step with a valid single-step task.
  
  
  
  Check for Typing Errors:
  
  Sometimes, the task ID might be mistyped or incorrect.
  Verify the task ID and correct it.
  
  
  
  
  Additional Information:
  
  
  Task Types in SAP Workflow:
  
  T (Single-step task): A task with one step.
  TS (Single-step task with container): Single-step task with container elements.
  M (Multi-step task): Task with multiple steps.
  MS (Multi-step task with container): Multi-step task with container elements.
  
  
  
  Transaction Codes:
  
  PFTC: Task maintenance.
  SWDD: Workflow Builder.
  SWI1: Workflow log (to check workflow errors).
  
  
  
  Related Notes:
  
  Ensure that the workflow step and task types are compatible.
  Review SAP documentation on workflow task types for detailed understanding.
  
  
  
  
  Summary:
  
  Cause: A non-single-step task was assigned where a single-step task is required.
  Solution: Use or create a single-step task (T or TS) and assign it to the workflow step.
  Check: Task type in PFTC, workflow step configuration in SWDD.
