To enable this capability, as part of linking asset to a trackable collection, system provides an option (through UI and API) to specify whether the asset “Is optional” - Yes or No. Default value is “No”.

Enable closing a trackable collection for modifications
The objective of this is to enable trackable collections to be modified/extended over a period of time, even after publishing them - without impacting the progress tracking. This is to support use cases where modules (sub-folders) within a course are periodically updated. Users can start consuming the modules as and when published. But the calculation of progress tracking happens only once the course is published with all the modules. Once the progress tracking starts, the collection will be closed for any further modification.
To enable the above, any trackable collection will have an attribute “Calculate progress ” “Open for modification” that can take values of “Yes” or “No”. By default it is set to “No”“Yes”. As long as the value is “No”“Yes”, the overall status of the collection progress is not calculated, because the collection might be undergoing modifications. Hence no certificates are generated.
Once the all the content is added to the collection, creator can change value from “Yes” to “No” to “Yes”. Appropriate warning is shown to the user when modifying this value. The same is shown to the reviewer when publishing the collection. Once the value is changed to “Yes” “No” and the collection is published, system calculates the progress based on the rules set for progress calculation.
Once a trackable collection is published with “Calculate progress” “Open for modification” value set to true“No”, the collection can no longer be modified.
...
Once a trackable collection is published, the collection can be modified only if the “Calculate Progress” “Open for modification” value is set to “No”“Yes”. If the “Calculate Progress” “Open for modification” value is set to “Yes”“No”, the collection can no longer be modified.
...
Once a trackable collection is published, the collection can be deleted only if the “Calculate Progress” “Open for modification” value is set to “No”“Yes”. If the “Calculate Progress” “Open for modification” value is set to “Yes”“No”, the collection cannot be deleted.
