Some use case needs to interact with multiple application and in such condition each application has its own way to handle the transaction and we can’t build one workflow for every application with there n no validations and conditions. it is always better to have separate workflow depending on which application we are going to work with current transaction and call only that application workflow.
It was just use case i have explain , but i really not understood why UiPath has removed this functionality from Invoke Workflow Activity. If you could add this feature asap that will really makes developer life successful.
