Example: We are connecting Jira and GitLab. Product owners using Jira want to send stories for development to GitLab. They are interested only in receiving updates on the stories - e.g. status, or comments. To achieve this we go to particular type mapping, Advanced tab, and enable Customize create / update actions feature. On Jira side we uncheck Create Task(s) checkbox, which means that tasks won't be created in Jira. We leave Update Task(s) checked, as we still want to receive updates.
