Bypass the 90-Day Limit: Incremental Load for Qlik Write Back

In our previous video, "Native Qlik Write Back is Here," we explored how to configure the new write-back feature. However, there is one critical limitation you need to be aware of: the native change history is only retained for 90 days.

To turn this feature into a permanent enterprise solution, you need to implement an Incremental Load.

Below is the script logic used in the video to fetch the change history via REST API, handle pagination, and merge the new changes with your existing historical QVDs.

For a step-by-step explanation of the logic behind this script, watch the full tutorial here:

The Code

This script assumes you have already configured a REST Connection to your Qlik Cloud tenant (as shown in the video) to fetch the change store data.

Next Steps

This approach ensures that even when Qlik purges the native change history after 90 days, you have a permanent, local record of every interaction in your QVDs.
