I have a custom field on my Campaign object that looks up to the Account. I am attempting to populate the Account field on the Campaign Object using process builder. We don't need any criteria, so I selected No Criterai for my criteria. This is an immediate action. I selected Update Record for the action and selected the Campaign record which started the process. When I try to select the Account field, I get an error which says "No Matches Found". I also tried to find other fields, but no mattter which field I try none of the fields can be found. I can't do this with Workflow because the Account is a lookup field. We are working with NSPS in nonprofit org, which means Salesforce support takes about a month to respond to inquiries. Does anyone have any idea how to resolve this?
