Do you have any idea if can we check what action a user has performed? I know that all posting actions are present in the Register, but how about updates that doesn’t affect any posting, such as the price on a PO? Or any Add-on can serve this purpose?
The standard Navision Change Log feature will allow you to capture any inserts, deletes, modifies on any table and records in Navision without any additional addon.
If you want to see whether a record has been accessed, you will need to use SQL Server to do that.
