Enter the key of the Efficy project (K_PROJECT) dedicated to the scanned documents.
Mind you, this is just one step in the configuration of the Efficy service Watch Doc!
Efficy users can scan documents with the command Scan Document of the Documents module.
Scanned documents can be processed from the Efficy user interface. Users go to the command Incoming Documents under the Tools menu to do so.
