In order to get a Workflow Service Input / Output other than the table connection you have to:

  • drag the connection of the type you want from the previous node

  • until a transparent plus sign appears

  • then you search for the "Workflow Service Output"

  • when you click this it will change the type from table to the type you were just dragging along ....

THX to Linh for this insight ...
