Please check to what workflow your Parameter file is going to ? and verify that you have the add or rename in the folder and state.
I have attached an Dispatch action to use Yes or No box.
Hope this helps,
Confirmation Window.acn.zip 467 bytes
I checked to make sure, and as admin I have full permission in the workflow and folders.
Good check though!
I'll check out your dispatch Thanks!
I see an SPR reported with the same problem as you have mentioned.
