Configuring the Lookup Set Filter tab for set codes
Using the Lookup Set form. This tab is displayed only for Lookup
Sets that have the V\
and V\REF
prefix.
Set code filters are optional. They restrict the list of views that are displayed in the Reports tab of the business object; and they restrict the list of reference choices that are displayed in the References tab of the business object.
Views and references are displayed for all business objects unless you specifically limit them to one or more set codes (classifications). You can limit them using the set filter functionality.
