Dynamic shares offer many different options to configure how you want to share data from your instance. These options include:
Share updates since then
Found under the Runtime Settings tab of the Standard view, this only tells the dynamic share if it should trigger for changes that are done through the user interface (UI) by a ServiceNow user (interactive only) or to capture any changes done, including those done in the background, such as scripting in scheduled jobs.
By default, this option is selected meaning only changes done through the UI are triggered and shared.
Enable debug logging
Found under the Advanced tab of the Standard view, this option enables debug logging that can be found under Troubleshooting for any execution of this dynamic share to help you troubleshoot issues with your sharing.
