How to show a question box before printing an invoice?

Question

1C-Enterprise

Hello. I use UT 11. Please help me with the following task.

When creating a Sales Order, when the user wants to print an invoice, i.e. presses "Print" -> "Invoice for payment", before showing the invoice, a window with a question should fly out. If the answer to the question is "Yes" -> Show the score. If "No" -> Leave in the order creation form.

The problem is that I can not find a place where exactly you need to prescribe the condition.

Answer 1

All you need to do is look at the code. May be implemented differently
