The approval process for updates to a modular questionnaire can differ depending on the setup. Updates may follow the same flow as a new questionnaire, go through a different approval process, or be automatically approved. If a project template includes an approval task for updates, the updates to the modular questionnaire must be approved before they are finalized.
If there are approval processes for the updates, or if you have requested additional information from the supplier, you can compare the answers in the latest and previous versions on the questionnaire details page during approval.
