How can I generate a report for each parameter element?

Question

1C

Hello. There is a certain report on the rests of the nomenclature in the prices.
Previously, you could select a price type as a parameter and view a report on it.
It was necessary to add the ability to select several types of prices for this parameter.
I added the possibility, but I face the following problems:
1. A report can have one "empty" type of price, where all resources are located in their rightful places, but in "non-empty" types of prices they look like one size fits all (i.e. if
somewhere there is no
value in any column, then it is automatically filled in from another. .
Nomenclature Kot, price type Wholesale, price 110.00
Nomenclature Kot, price type Retail, price 85.00
Nomenclature Kot, price type Wholesale, price 85.00
But if the prices are taken "as it should be", then everything is safely screwed up and a situation arises with an empty price block.
Unfortunately, I can’t provide a query for corporate reasons and because few people want to shovel almost 1000 lines.
Therefore, I do not hope for exact answers, I would like to hear assumptions.

Create a simple analogue of the request (10-20 lines), throw it here - then maybe they will prompt.
