Here's how you can prevent any report from being published. You'll still see the 'Publish' link but this will prevent it from being saved. A report is published any time it is saved with the 'public' role. You can see the 'roles' field by navigating to the report table to verify. The front-end UI will make it look like the report can be published...and has been published...but it won't actually save on the back-end. It's not great, but it's the best you can do.
1) Navigate to 'Reports -> Administration -> All' in your left nav.
2) Right-click the list header and select 'Configure -> Business rules'
3) Create a new business rule with the following settings...
Name: Disallow publishing
Advanced: True
When: Before
Order: 1000 - This is important in order to abort correctly!
Insert/Update: True
Condition: current.roles.changes()
Script:
(function executeRule(current, previous /*null when async*/) {
var roles = current.roles.getDisplayValue();
if (roles !== null) {
// Check for the 'public' role
var n = roles.indexOf('public');
if (roles.indexOf('public') > -1) {
// If we find it abort the update
gs.addErrorMessage("Cannot save as a public report. Please remove the 'public' role and try again.");
current.setAbortAction(true);
}
}
})(current, previous);
