    SAP Error Message:
    WTYC1001 No sequence can be maintained for action &1 (invalid type)
    
    
    Cause: This error occurs in SAP Workflow when you try to maintain or define a sequence for a workflow action, but the system does not allow it because the action type is invalid for sequencing. In SAP Workflow, certain action types do not support sequence maintenance. For example, if the action is of a type that is not a standard workflow step or is not designed to be sequenced (like a container assignment or a method call that is not sequencable), the system will throw this error.
