I have three custom objects: Sale, Expense and Lead Source. Lead Source is a parent object on both Sale and Expense. I’ve created two Aggregate Models that work fine and show the following: Sales Per Lead Source (Aggregates Sales Model that Groups by Lead Source) Lead Source---------- —Gross Profit Cars.com -----------------$10,000 Autotrader.com---------$11,000 Expenses Per Lead Source (Aggregates Expense Model and Groups by Lead Source) Lead Source--------------Total Expenses Cars.com------------------$5,000 Autotrader.com----------$4,000 Is there a way to combine the results from the two models. In my case, I’m trying to calculate the Marketing Return on Investment for the company’s various lead sources. Formula is (Gross Profit - Expenses) / Expenses. Ideally, the table would like the following: Lead Source----------Total Sales-----------Total Expenses-----------Return on Investment Cars.com ----------------$10,000-------------------$5,000-------------------------100% Autotrader -----------------$5,000 ----------------- $4,000--------------------------25% Is this possible using Aggregate Models in SKUID? Any help steering me in the right direction is sincerely appreciated.
