Problem with 1C request, why doesn't it work?

Question

1C

Good afternoon, I ran into this problem. It is necessary to organize a selection for all documents, the documents have a tabular part from which, in fact, you need to unload. I write a request in the console, it works, I transfer it to the code, it does not work with the appropriate edits.
Moreover, by default, it will unite any selection from the table into one line, if you do not force it, it will not split it. when processing a request through a normal request, there are empty positions when everything works properly in the request console. It is necessary to do it through documents, not to offer savings according to registers.

Answer 1

If you want to get a tabular part, then you need to pull it out in the document, select it, and not the document itself, and also about the "empty" positions, did you set the query parameters?
