Environment

SAP SuccessFactors Learning Management System (LMS) - All Supported Versions

Cause

After the user was assigned with the course, an admin performs changes in the Content Object within the item level but does not reassign the course to the user.

Resolution

 ***Important Note: If an item with online content has been assgined to users, and the content objects need to be updated or the online content section needs to be updated ( by adding a new content object, attempting to replace/edit an already added content object is not supported), it is recommended to revise the item or create new item prior to adding or updating the content so that the ingerity of the prior content can be retained. Failure to do this can result in un-recoverable issue with Learning history and Data reports***

Remove the course from users' learning plan and assign it back OR use the content re-assignment wizard as per the KBA 2328118.
