How can we allow just record edit through UI(not create, not delete)?

Use a workflow to restrict creating & deleting - filter on the record type

Thanks Any other solution?

What have you tried?

You could use a UserEvent on the record in beforeLoad and check the context and do whatever you want it to on CREATE or DELETE

@Sandii how can I show an error and stop loading record for example when user wants to delete the record

You need to play with but probably need beforeSubmit and check the

context.type

and use

throw

to throw an error instead
