It is possible to share VendorLink reports, at organizational and user level. Click here to read more about sharing dashboard reports.
When others then open the report to those who created the report, VendorLink will check per tile whether this person has the correct rights to view the data.
This also applies to the users assigned to the report. You may not want these users to be able to use the other modules.
You want to share a report with data about a particular cost center with a user. For this the user in question needs the role 'Spend Viewer' rights to be able to consult the tables and graphs in the report. If you want to prevent this user from seeing all other spend in the Spend module, you can activate the 'Hide modules' checkbox for the user under Admin > General Settings > Users. This way you prevent the user from seeing this module after it has used the link.
