• What is the cause and solution for SAP error message WF108 - Action <&> is not allowed ?

  The SAP error message:
  WF108: Action <&> is not allowed
  
  Cause:
  This error occurs in SAP Workflow when an action that is not permitted in the current context or status of the workflow container or task is attempted to be executed. Essentially, the workflow engine is trying to trigger an action that is either:
  
  Not defined for the current workflow step or task.
  Not allowed due to the current status of the workflow or container element.
  Restricted by the workflow definition or authorization settings.
  
  For example, the workflow might be trying to execute an action that is not assigned to the current task or the action is not valid for the current object type or status.
  
  Solution:
  To resolve the WF108 error, follow these steps:
  
  
  Check the Workflow Definition:
  
  Go to transaction SWDD (Workflow Builder).
  Open the workflow and check the step where the error occurs.
  Verify that the action mentioned in the error message is correctly assigned to the step or container element.
  
  
  
  Verify Action Validity:
  
  Ensure the action is valid for the object type and status.
  Check the method or function module linked to the action to confirm it is active and allowed.
  
  
  
  Check Container Elements:
  
  Verify that the container elements passed to the action are correct and consistent with the workflow definition.
  
  
  
  Authorization Check:
  
  Confirm that the user or system executing the workflow has the necessary authorizations to perform the action.
  
  
  
  Debug the Workflow:
  
  Use transaction SWUS or SWI1 to monitor the workflow.
  Use the workflow log to identify the exact point of failure.
  Debug the workflow to see why the action is considered not allowed.
  
  
  
  Check for Custom Enhancements or Exits:
  
  If there are any custom enhancements or user-exits influencing the workflow, verify that they do not restrict the action.
