The Data Share Report provides a summary of what data fields are being shared with each vendor, along with the number of active and inactive records. It can be found in the "Logs" section of the RosterServer console, under the Audit Log.
Fields that are not being shared with a vendor will be indicated in the report
In addition, the report can be searched in two ways- by app or by table. Searching by app searches by app name. Searching by table allows you to search for a collection (for example, orgs) so you can see what fields are being shared for the orgs collection for each app.
The report can be exported as a .PDF by clicking the "Download Report" button in the top right.
