NSc Sync v2.1.0.42 contains an update to the ProductNavigation Table in NSc Sync to address a compatibility issue with Alternative (Web) Navigation.
If you notice E1350 errors on the Summary Tab for the ProductNavigation Table, and specifically errors on the Log Tab to the effect “Invalid Column Name WebDepartmentID” (as seen below), then we would recommend that you upgrade to NSc Sync v2.1.0.42
