How to Prevent Data Change looking at Secondary Assignments

Summary:

Hello,

I have created a data change for Salary changes. However the system is picking up changes in secondary assignments. It is also picking up new secondary assignments as salary changes.

For example, my primary assignment has no changes since 6/25. However, I added a second part time assignment on 7/1. System is creating a Salary Change Life Event using the secondary assignment info.

How can I make it only look at primary assignment changes, please dont say fast formula :)
