the system requirements can be found in the help portal. Here is a direct link to them: http://help.docuware.com/en/#b57853t55049n87396
how is the iPad app downloading documents from DocuWare to the device?
Auditing is now part of the DocuWare Configurations since version 7. You can find information on this here.
it looks like the file cabinet is not assigned to the document tray that the document is placed by DocuWare Printer.
Please check in document tray configuration which file cabinet is assigned to the tray.
Integration links are always opened independent from the web client. It is not possible to open them right there.
this should all be possible with one Autoindex Job. Autoindex can write to the external database also and set the new field to 1 if the data was assigned to a DocuWare document. In the newer versions (version 7) of Autoindex this is in the tab "Write back".
With DocuWare version 7 you should maybe think about switching to an event based Autoindex. In this case, there is just a small query executed whenever a new document matches the trigger. The load should be much less, than if you do a complete database query for all relevant data entries.
I hope this helps.
