I am confused on a test question about setting access to a custom object. The answer is: Set the OWD to Public Read Write, Give the product team CRED in permissions Give the Executive profile read only. Considering these are the only two groups to have access to the object, why isn't the OWD set to private'

What is the status of this?  Can we get any updates?  It's been 11 years (5 since the last comment from Salesforce)

Idea: Record Type Assignment Tool for Profiles

Not for nuthin' but the only thing "quick" about the Quick Find box in Lightning Setup is how fast it freezes when you try to type something in it.

I want to create a Lightning web component which should have the facility to add expenses records as a row. Each expense record should have expenses type, date, amount, and expenses attachment. There should be a button which will initiate the approval of the expense record. There should be an add button to add a new blank expense record and a button to delete expense record which are not approved. The Lighting web component should have the functionality to save the entire expenses form and retrieve it later to add more expenses or submit the entire form (all the expense records ) for approval.

I would like to know how do I create such Lighting Web Component?
