You are able to select and deselect metadata and optional fields so that they either accessible or inaccessible to certain vendors.
Navigate to the "Filter Fields" option in the OneRoster Application drop-down menu.
From the Filter Fields window, you are able to deselect fields you do not want to get sent to the vendor. By default, all fields are selected.
NOTE: If you only want a particular metadata field to get sent to one vendor, you must make sure that ALL other vendors have that field deselected.
The vendor's data will get updated the next time they pull data from Roster Server.
