How to create a new report in a 1C demo configuration?

Question

1C-Enterprise

Hello, I need to create my own report in the constructor based on 1C accounting (demo). I made the simplest report in the constructor, launched it in enterprise mode, opened my report, pressed the generate button and received the following message:
Report generation failed: In the "Connect Report AND Load Settings" method, the parameters "Variant Link, Report Link, Variant Key" are not specified. Tell me what to do with it?

Answer 1

1) If the report is opened via File / Open, then there is no such error (although xs, what's inside the report).
2) If a directory of external reports is used, then when creating a report, implement the program interface - read the details in the help.
