Declarative Apex Roll-Up Summary Framework

Problem

Standard Salesforce roll-up summary fields only work on master-detail relationships. Calculating roll-ups across lookup relationships or more complex logic requires writing custom triggers for each object, which is inefficient and hard to maintain.

Solution Overview

This framework provides a custom metadata-driven solution. Admins define the roll-up logic (parent object, child object, fields to aggregate) in custom metadata records. A set of generic Apex triggers handles the calculations, making it scalable and reusable.

How to Deploy

1. Download and deploy the Apex classes and custom metadata types.
2. Create a new Custom Metadata record for your desired roll-up.
3. Specify the Parent Object, Child Object, Relationship Field, and aggregation logic.
4. The framework's trigger will automatically handle the rest.
