About this question
I have created a Multi Select picklist field on Account(Service Partner Type). I wanted to add criteria that would filter by "Service Partner Type" includes/contains "Certified Implementation Partner (CIP)," but since it is a multi-select picklist value, I couldn’t.
Then, I added a checkbox to the account and used WFR so that it becomes true when Service Partner Type= 'Certified Implementation Partner (CIP).' The checkbox field is added as a lookup filter criteria.
When the Service Partner Type field on the account is filled up with a value, the Service Partner Type field on the Project is also filled with the same value. If I want to populate a multi-select picklist field values onto another multi-select picklist field) Then, I use Apex.
When I edit an Account, I get the below error:
