Prerequisites

Prerequisites (also known as dependencies)

If a component has a prerequisite configured, then you are essentially letting the system know that this component should not begin until the pre-requisite has finished. So if a user attempts to activate such a component, the system will trigger a prompt window to confirm that you wish to activate even though one or more pre-requisite tasks are not completed.

Once you have addded some pre-requisites between your components, the Schedule tab on your job will reflect this by staggering your components:

You don't need to order the components in your workflow according to their pre-requisites - but your workflow will be easier to understand if components are ordered this way!

1. Open the Edit Workflow screen, then click on a component to modify it, and under the prerequisites section, click All Available components. If there are none there, you might have only just created this component, in which case try saving and trying again.
2. Under All Available you are able to select which components will be made pre-requisite to the component you are editing.
3. As you place a tick against a component here, it will add it to the Pre-requisites tab just to the left. Click this tab to review any pre-requisites that have been added:

As a component is checked to be a pre-requisite, it is added to the Pre-requisites tab.

• To remove a pre-requisite, click the red x next to it, and then save your changes.
