You can add and remove dependencies from a category when you add or edit the category. An ancestor or parent run identifies the category that this category is dependent on.
In order to run a category with a parent, you need to have completed parent runs available that the run for this category incorporates. If you haven’t run the parent category, you can’t run the associated category. For example, most FA runs require an IC run and all Reserve Runs require a Pairing Run (consecutive reserve only).
When launching a reserve run a valid pairing run from the same category must be selected as the parent. Ancestor, Parent, and Child information is displayed in the Run Detail Pane. Refer to the Run Detail Pane article for further information.
