After the user was assigned with the item, an admin performs changes in the Content Object within the item level (at the item's record > Online Content tab), but does not reassign the item to the users.


 ***Important Note: If an item with online content has been assigned 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***

To make the users already assigned with the item in question are updated with the latest changes done to the contents within the item level, there are two options:

  • Remove the items from the users' Learning Plan and assign it back; OR
  • Use the content re-assignment wizard as per the KBA 2328118
