By default the record view layout will be picked according to the custom layout you have defined in the provisioning tool. In case you don't have any custom layout then the Business entity view will be picked. It will use the same layout for both read and write scenario.
Thankyou for the reply. Our use case is that when we want to import the data from the third party application (eg- D&B) and want that data to be non-editable. And on the same screen user should be able to fill the information for other child entities.
Thanks & Regards,
