An organization is designing a data model where the Account object needs to aggregate data from multiple related Opportunity records. Due to business requirements, they need to track sum of amounts, count of opportunities, average deal size, minimum opportunity amount, and maximum opportunity amount. Additionally, they require roll-up fields for several custom objects. During their review, they discover that their current design includes 26 roll-up summary fields on the Account object. What issue will they encounter?

  • A. The system will automatically delete the oldest roll-up summary field to maintain compliance
