How to make a simple report (just learning)?

Question

1C-Enterprise

Hello. Learn the basics of programming in 1C. I started with a free course on the 1C website. They invite me to work, they know that I have no experience, they said they will train me, but if I only do a test task. The task seems to be simple, but if you do it at the rate that is on the 1C website, then I get not much that needs to be done. In general, the essence of the task:

Task - "Cashier"

In an empty configuration, create:

1. Directory "Counterparties"
2. Two documents - "Incoming money" and "Expending money"
3. Report "Money flow" for the period with details on counterparties

Details of documents :

1. "Counterparty" - from whom the money was received or to whom it was transferred.
2. "Sum" - numeric attribute
3. "Base" - string attribute, length 100 characters

The report is intended to obtain information when, from whom and how much was received and to whom it was transferred.

I sincerely ask you not to voice ready-made solutions, but simply to push in the right direction, I want to do it myself.
I made reference books and details. A little unclear with the report. At the rate I did through the savings registers. Then through reports transferred. But I got a report, where only the Counterparty and the amount (well, income or expense). Please help me figure out how to do it. Let me remind you, I want to do it myself, you just need a kick in the appropriate place)))

PS. I opened 1C programming (configurator) only yesterday. Please do not swear, everyone started somewhere)

The general principle is as follows: The document makes movements in the register ; it can be the Information Register, the Accounting Register, the Accumulation Register; Movements are programmatically made when holding a document;
Report - must use a request to apply to the corresponding register, with a selection of the type Registrar = LinkToDocument; The result is then looped over and output to a SpreadsheetDocument;
