Hello. When we create Customer Payment using SuiteScript, could I know how to select Deposit please?

let pymtRec=record.create({type:record.Type.CUSTOMER_PAYMENT, isDynamic:true});

When I get line count for "Deposit", I can see there are 2 deposits but according to record browser, there is no internal id for that "deposit" sublist and internal id. So I can't sure which deposit is which one.

I think

doc

is the id

Thank you
