User Story:
As a finance manager,
I need the system to automatically keep track of an event's gross revenue by taking a sum of all accepted sponsor's contributions,
So that we can maintain an accurate and real-time tally of an event's gross revenue and ensure that financial reporting reflects all accepted sponsor contributions.
Acceptance Criteria:
- When a CAMPX__Sponsor__c record is updated to have an "Accepted" CAMPX__Status__c, the system should account for the sponsor's CAMPX__ContributedAmount__c in the CAMPX__Event__c's CAMPX__GrossRevenue__c field
