Add a Budget Status Column to the CampaignsList. This is done by deriving a new column in the view called 'vCampaigns'. The derived field will show whether Campaign costs are within budget 'Green', approaching the budget limit 'Amber' or have exceeded budget 'Red' by using a simple icon display similar to the Case SLA Status field. The budget warning level 'Amber' is set to be 90% of the budget.
