Can we map a function key to unknown document type ?
No we cannot map a function key to unknown document type as the function key Mapping is made assigning the function to a specific document type, and the Unknown document type is not managed by the batch class management.
To map a function key with unknown document type below needs to be done:
Create a new document type which will be mapped to all Documents classified as Unknown, Now in document assembler plugin, we have a property called “Change Unknown Document Type”, here you can assign the Documents classified as Unknown to the newly created document type.
Now you have the Unknown documents map to a specific document type and now you can assign a function key over the new document type having documents classified as Unknown.
