Master-Detail form - Insert into Detail form app

How can SC clone/copy values of the ‘Detail’ form (refer before.jpg) and paste into ‘Detail’ form when i clicked ‘Add’ in Detail form?
What i realized, currently SC only copied the Foreign Key :frowning:

It shouldn’t be fetching the values from DB because might consider i add 5 ‘Detail’ rows before click on ‘Save’ button.
I am looking for a way SC can read from LAST ‘Add’ row (and not inserted into DB)

Kindly advice

First of all as you are working record by record you need to hit save on every new detail record. The save button doesn’t work on the master afaik. What SC is copying since it’s a master-detail is the primary of the master. That’s a normal behaviour as this is ‘the linking pin’. If you need to change this value you need to set it in the properties as initial value or by one of the events.
