How to prevent users from enrolling in multiple events (covering the same topic)

Applies to: Event Management for Office 365/SharePoint online

This article will show you how to limit the number of enrollments per user within a topic. This is relevant, if you have a topic with multiple events and you would like users to be able to enroll only in one of them to avoid multiple registrations.


Make sure you have the app SharePoint|sapiens Modern User Interface version or higher installed. Here you can download the latest version. After installing the new version, open the Site Contents view on your SharePoint site, click on the app SharePoint|sapiens Event Management, click on Change Settings and save the settings again.

Add the column Max. Enrollments per User to your course form

Once you created your topic click on Edit Form in the top right-hand corner

click here to edit form

Click on the + sign and select the column Max. Enrollment per User


click here to add the max enrollments per user column

This column will prevent the same user to register for two events within the same topic.

For example: it will be possible for a user to register only to one of the appointments for the Mobile Health Check.

Once the column is added save the form by clicking on Save Form Changes

Enter a value in the column Max. Enrollments per User

Open the course form and click on Edit on the top left hand-side of the form. Add the number of maximum enrollments that you would like to allow per user for this course. And click on save.
