How to work with EPD

Question: It is not clear how EPD (early payment discount) works:

1. I create a sales invoice with EPD.
2. I register a bank receipt for this invoice within the period of EPD.
   1C:Drive shows that EPD can be applied, but does not apply it.

How can I register the fact that the customer has paid less because of EPD?

Answer: In the bank receipt, before posting it, go to the Payment allocation tab and click Fill. The EPD column will be populated for the filled in line.
