This problem analyzer helps deploy missing dependencies between components.

If you try to deploy an item without a component that it depends on, the analyzer will also suggest including that dependency in your deployment package. 

These suggested items will have been detected by Gearset in the source environment of your deployment but cannot be found in the target.

Within Gearset's UI the following problem message will be presented, along with a list of the components that the analyzer suggests you include in your deployment. Checking the boxes will include the suggested components in your deployment package.

When deploying items without the components they depend on, your deployments will most likely fail.

Gearset will automatically add the missing referenced components that you specified to the analyzer to include to your deployment package. This will make your deployments more likely to succeed.
