Search for related products within the database

[mraka9]

Greeting,
I have a large database in which it is possible to identify related products based on: item number, group, item.
I tried to connect these items and now I want to make a table in which I will have data that are related products.

Example:
Car-12 appears in three places and its related products are visible.
I would like to have a unique table where for each item I have a list of its relatives.

The database is quite large, so I would like to ask for help on how to do it and make it optimal for use.

Thanks a lot in advance!

@mraka9 can you share a sample data as a table here so I could copy paste it to PBIX

Thanks in advance

Item number	Group	Stavka	Item	Summary data
10-1	1	1	Car-12	Car-12;Car-14
10-1	1	1	Car-14	Car-12;Car-14
10-1	1	2	Bike-77	Bike-77;Bike-99
10-1	1	2	Bike-99	Bike-77;Bike-99
20-1	1	1	Car-12	Car-12;Car-42;Car-33
20-1	1	1	Car-42	Car-12;Car-42;Car-33
20-1	1	1	Car-33	Car-12;Car-42;Car-33
20-1	2	1	Mobile-444	Mobile-444;Mobile-333
20-1	2	1	Mobile-333	Mobile-444;Mobile-333
30-1	1	1	Car-12	Car-12;Car-69;Car-777
30-1	1	1	Car-69	Car-12;Car-69;Car-777
30-1	1	1	Car-777	Car-12;Car-69;Car-777

@mraka9 I wrote this calculated table:

Result = 	
SELECTCOLUMNS(
		GENERATE(
			ADDCOLUMNS(
				VALUES('Table'[Item]),
				"@List", CALCULATE(CONCATENATEX('Table', 'Table'[Summary data], ";"))
			),
			VAR _current_item = 'Table'[Item]
			VAR _current_list = [@List]
			RETURN
				SELECTCOLUMNS(
					FILTER(
						VALUES('Table'[Item]),
						'Table'[Item] <> _current_item
							&& CONTAINSSTRING(_current_list, 'Table'[Item])
						),
						"Related item", 'Table'[Item]
				)
			),
			"Item", 'Table'[Item],
			"Related item", [Related item]
	)

Maybe it will work on the full data, but on the sample I'm getting something else for Car -14.
The thing is, can you please explain why an item is a related item. For example, why car 14 has car 33 or ca4 69 as related?

Thank you very much!
This is a genius solution.
You are right, the link is provided in the sample because of the smaller sample.
This is definitely the solution to my problem!
I hope it will also work on large amount of data!

Thanks again!
