Microsoft Dynamics NAV’s Incoming Document helps the user to efficiently upload and reference outside documents within their ERP database. Incoming Documents may be attached to unposted documents or journal lines and follow the posting to the resulting entries throughout NAV, notably posted documents and ledgers.
If you want to add files to a nav document like orders, then you normally use the link factbox. For that you have to link files on file shares, local paths are not allowed (not reachable from other systems). savedocsThat only works, if the current user has the needed permission and the network path is reachable. There is also a problem, if the file is moved, deleted or the permissions were changed.
