This feature minimises human error and makes the Client Service function much easier when creating a Job Bag. You can use it to shortlist the available Campaign names once a product has been selected.
It provides a way to restrict certain users from selecting other non-related campaigns. In the case where Campaigns are only created on the Client Details page, only specific users will have access to edit them. So it ensures minimal chance of error and easier administration.
To use this feature, the Product needs to be set within the Campaign field in the Client set-up screen.
