This is a "better write it down for the future me" post.
For the TL;DR pals, this is the Github repository.
It was years I wans't working with Campaigns, so it took me a while to remember a simple thing: you cannot automate
Campaign Member Status configuration with point & click.
It seems awkward, mostly because you have a Status picklist field on the Campaign Member.
And when you cannot find the New button on the picklist related list of that field you start feeling depressed.
After a while (you don't really need much time, just google it a bit) you find out there is a wonderful Campaign Member Status object, that holds the details of a specific Campaign's members statuses.
Then you learn (again) that you need to use the Advanced Setup button (in Classic) or the Campaign Member Status related list (in LEX):
When you add a new value the list of values in the Campaign Member Status is automatically updated:
So the next question is:
How to automate this?
Well, unfortunately you can't, you have to manually create the Campaign Member Status values on every Campaign you create.
If your users create campaigns often, believe they won't accept it as a solution!
As a simple solution we can:
- correlate Campaign Member Status values to Campaign Record Types
- store Campaign Record Type / Campaign Member Status Value couples inside a Custom Metadata object
- implement a trigger that executes on campaign create or if its record type changes
CampaignMemberStatusConfiguration__mdt
Name and Label standard fields will not be used to store actual values for our feature implementation, becausr they can only store 40 chars that is definitely less than 80 required for Record Type Developer name and 765 required for Campaign Member Status value (we'll be using max 255 chars in this implementation).
Campaign Record Types
Custom Metadata values
Apex Code algorithm
The following code, invoked from the Campaign trigger, calculates the new Campaign Member Status objects, removing the old one and creating the new ones.
