  Error Message
  WFRE_CON304: No Assignment Data selected and Transferred
  
  Cause
  This error occurs in SAP Workflow when the system tries to transfer assignment data (such as organizational data, user assignments, or container elements) from one workflow step to another, but no relevant assignment data is found or selected for transfer.
  Common causes include:
  
  The workflow container or task container does not have the expected assignment data.
  The assignment method or rule used to determine the responsible agent/user is not returning any results.
  The organizational assignment or user determination logic is missing or incorrectly configured.
  The workflow step or task is not properly linked to the assignment data.
  The workflow container elements required for assignment are empty or not populated.
  
  
  When does it occur?
  
  During workflow execution, especially when the system tries to determine the agent(s) responsible for the next step.
  When using assignment methods that rely on organizational management or user determination rules.
  When transferring data between workflow steps or tasks and the expected assignment data is missing.
  
  
  Solution / How to fix
  
  
  Check Assignment Methods:
  
  Verify the assignment method configured for the workflow step or task.
  Ensure that the method or rule used to determine the agent is correctly implemented and returns valid results.
  Test the assignment method independently (e.g., via transaction PFTC or SWDD).
  
  
  
  Verify Workflow Container Elements:
  
  Check the workflow container elements involved in assignment.
  Make sure the container elements are correctly filled before the assignment step.
  Use transaction SWI1 or SWIA to analyze the workflow runtime and container content.
  
  
  
  Check Organizational Data:
  
  If the assignment depends on organizational management (OM), verify that the organizational structure is correctly maintained.
  Ensure that the user or position exists and is active in the OM.
  Use transaction PPOME or PPOSE to check organizational assignments.
  
  
  
  Debug the Workflow:
  
  Use the workflow debugger (transaction SWUS) to step through the workflow and see why no assignment data is selected.
  Check the return values of the assignment method.
  
  
  
  Check Custom Code (if any):
  
  If custom assignment methods or rules are used, verify that the code correctly returns the agent(s).
  Ensure no runtime errors or empty results occur.
  
  
  
  Review Workflow Logs:
  
  Use transaction SWI1 or SWI2_FREQ to check workflow logs for more detailed error information.
