  Error Message
  WF102 Link & does not exist
  
  The ampersand (&) is a placeholder for the actual link name or ID that the system is trying to reference.
  
  
  Cause
  This error occurs when the workflow runtime tries to access a link (a connection or relationship between workflow container elements or tasks) that has not been defined or has been deleted. In SAP Workflow, links are used to connect workflow container elements or to pass data between steps. If the workflow definition or the runtime environment references a link that does not exist, the system raises this error.
  Common causes include:
  
  The workflow definition was changed, and a link was removed or renamed, but the runtime still tries to access the old link.
  The workflow container element or link was deleted or corrupted.
  Custom workflow development or modification introduced inconsistencies.
  Transport or system copy issues where workflow objects are not properly transported or activated.
  
  
  Solution
  
  
  Check Workflow Definition:
  
  Go to transaction SWDD (Workflow Builder).
  Open the workflow definition.
  Verify that the link mentioned in the error message exists in the workflow container or between steps.
  If the link is missing, either recreate it or adjust the workflow logic to remove references to the non-existent link.
  
  
  
  Check Workflow Container:
  
  In the workflow builder, check the container elements and links.
  Ensure that all container elements referenced in the workflow steps are properly linked.
  
  
  
  Activate Workflow:
  
  After making corrections, activate the workflow again to ensure all changes are saved and active.
  
  
  
  Check Runtime Logs:
  
  Use transaction SWI1 or SWI2_FREQ to check workflow logs.
  Identify the exact step or container element causing the error.
  
  
  
  Transport and System Copy:
  
  If the issue appeared after a transport or system copy, verify that all workflow objects were transported correctly.
  Re-import or re-activate workflow objects if necessary.
  
  
  
  Debugging:
  
  If the problem persists, debug the workflow runtime to see where the link is being accessed.
  Use transaction SWUD or debugging tools to trace the workflow execution.
