The "Data filter" settings of the VPS

The "User Setup" dialog lists your data filters 

Data filters work as Dynamics 365 BC filters on reading the data (either when the VPS is started or on reloading) so that they are already effective at the data interface to make sure that only filtered data is handed over from Dynamics 365 BC to the VPS.

The "Data Filters" area

This area informs you which data filters are currently active. The filters themselves are created and edited in the "Edit Filters" dialog (see chapter Data Filters). You can apply filters for work centers, work center groups, machine centers, and production orders.
