Mitch Morrison Apex trigger changing event value from contact field change - NOT WORKING
Hello, I have a trigger that works for my test class, but in implementation, it doesn't work. When the field "YTD_sales" changes on a contact, the trigger should increment the field "Sales within 1 Year" for every event tied to the contact.
Right now, only some event values get updated, and it is especially problematic for multi-person events (which I tried addressing through event relations). The batch size of the import could be an issue (its 10,000)
Let me know if you have any thoughts! Thanks!
(I'll post the code below)
