How to change orders unloaded in 1C?

Question

1C

There is a self-written stray that uploads orders to UT 11 from an online store through the Bitrix module.
The initial upload goes fine, but when I change the order on the site, I can’t force the order to change in 1C, it writes either “Since the last download from the BUS, the document: The order of the client XXXXXXX from XXXXXXX has not changed. The document will be skipped.”, Or if I slip the number that came from 1C, new order.
Tell me where to get examples of xml-uploads.
PS The store is on rails, some ready-made solutions for integration with 1s may have appeared.

Answer 1

Open the 1C configurator, find these words with a global search and look there.
Perhaps this will help.
