How to Add 'Orders' table for Checks and Payments entity in Endpoint

Hi, 

In my Acumatica 21.211.0033 I need to configure endpoint in such way that I will have an ability to generate Checks and Payments item with type Prepayment that will have ‘Documents to Apply’ table and ‘Orders’ table

I have already found and added ‘Documents to Apply’ table

But I can’t find ‘Order’ table for checkes and payments. What’s it’s name ? Can it be added for using in creating new ‘Checks and Payment’ item with type ‘Prepayemnt’ ?

I need something like this
