Why can't I set up an exchange of orders with the 1C website?

Question

1C-Bitrix

Friends, I have the following problem. I'm trying to set up an exchange of UT (11.1.10.180) with the site through the exchange nodes with the site. It unloads goods and prices remarkably, but if I check the exchange of orders, then the fields appear required to be filled in: “Order date on the site” and “Order number on the site” (the fields are empty by default). When you try to select an attribute, a form for creating an additional attribute opens. Created a new attribute, but it is not displayed in the selection form. Is this a bug or am I doing something wrong?

Answer 1

go to any customer order, then press the button More -> Change the composition of additional details
you will open a directory of additional details, while the desired composition will be immediately highlighted and in the left window you will need to create an additional attribute:
Order date on the site, value type - date
Number order on the site, value type - string
