Define the input parameters for the chosen action on the Input Parameters tab:

Search filter
The search filter parameter applies to the actions Index, Attach attachment to document, Attach PDF to document, Export document as attachment, Export document to directory, Delete document, Read index data, Copy document, and Move document.
Here you specify the document to be the object of the action. Do this using a search filter. The filter must be able to uniquely identify the document.
All filter criteria will be connected with the AND Boolean operator.
Index
Here you can define the DocuWare file cabinet fields that must be filled with the values from the JobRouter.
