I turned on Campaign Influence and it appears to be working correctly. When a contact is added to a campaign, that influence is showing in the new related list of the opportunity.
Primary campaign source is getting 100% attribution.
We want to move to an even distribution of influence(%) for all campaigns on a given opportunity. I was able to use dataloader to populate all legacy opps but I'm not clear on how to do that going forward.
I understand that I would create a new model(Customize >> Campaigns >> Campaign Influence >> Model Settings) for the even distribution, let's call it
SFDC videos and docs all show you how to create/change the
Campaign Influence Model but gloss over what happens next.
Do I need code to do this? Is there some boilerplate? I can't be the first person to try to do this.
