  Error Message:
  WZ098 - Single-step task could not be created
  
  Cause:
  This error typically occurs in SAP Workflow when the system tries to create a single-step task but fails. The reasons can include:
  
  
  Missing or Incorrect Task Definition:
  
  The single-step task that the workflow is trying to create does not exist or is not properly defined in the system.
  
  
  
  Authorization Issues:
  
  The user or workflow agent does not have the necessary authorizations to create or execute the task.
  
  
  
  Incorrect Workflow Configuration:
  
  The workflow step is incorrectly configured, e.g., the task is not assigned properly or the container elements required for the task are missing or incorrect.
  
  
  
  Technical Issues:
  
  Problems with the workflow runtime environment, such as inconsistencies in the workflow tables or issues with the task repository.
  
  
  
  Missing or Incorrect Agent Assignment:
  
  The system cannot determine the agent (user or role) responsible for the task, so it cannot create the task instance.
  
  
  
  
  Solution:
  To resolve the WZ098 error, follow these steps:
  
  
  Check Task Definition:
  
  Go to transaction PFTC (Task Maintenance).
  Verify that the single-step task exists and is active.
  Check that the task is correctly defined as a single-step task.
  
  
  
  Verify Workflow Step Configuration:
  
  Use transaction SWDD (Workflow Builder).
  Open the workflow and check the step that triggers the single-step task.
  Ensure the task is correctly assigned and the container elements are properly mapped.
  
  
  
  Check Agent Assignment:
  
  Verify that the agent determination for the task is correctly set up.
  Use transaction SWI1 or SWI2_FREQ to check workflow tasks and their agents.
  Make sure the agent(s) exist and have the necessary authorizations.
  
  
  
  Check Authorizations:
  
  Ensure that the user or workflow agent has the required authorizations to create and execute the task.
  Use transaction SU53 after reproducing the error to check for missing authorizations.
  
  
  
  Check Workflow Logs:
  
  Use transaction SWI1 or SWI2_DIAG to analyze the workflow log for more detailed error information.
  Look for any additional error messages or warnings related to the task creation.
  
  
  
  Consistency Check:
  
  Run workflow consistency checks using transaction SWU_OBUF or SWU3.
  Fix any inconsistencies reported.
  
  
  
  Transport and System Issues:
  
  If the task or workflow was recently transported, verify that all objects were correctly imported.
  Check for any system inconsistencies or database issues.
