Is there a way to auto-populate the fields based on the lookup field while user is on the New record screen? Example, Let's say I have custom object called Project. I have a lookup field "Master project" that is a lookup on the same object. When a user tries to create a new record and selects a project in that master project field, it populates certain fields before the user saves the new record, based on the record in the lookup.
New Project ==> New Project Screen opens ==> User selects a record in a lookup field ==> auto populates certain fields ==> Users review/changes the data in auto-populated fields ==> Saves the new record which closes the New project Screen
I know I can use a flow to update those fields after a new record is created but I want to see if there is a way to update those fields while the record is being created.
