Filter all records from an order if the order contain one specific product

[luigiPulido_]

Hello there,

The business problem is that I download a table from shopify where I have the order with all the items that are in that order. The problem is that  orders that has (in this case) the Product 'bbbb' need to be handle different with all  the products in that order.

In this case this the comple table

And this is the table that I need at the end where only order 1 and 4 has product 'bbbb'

I tried with data nesting and some filters but to be honest I am not very good with powerquery and M lenguage. My plan B is Macros or Array formulas in Excel but I prefer to  learn something new with power query.

Hello, @luigiPulido_ 

let
    Source = your_table,
    orders = Table.SelectRows(Source, (x) => x[Product] = "bbbb")[Order],
    z = Table.SelectRows(Source, (x) => List.Contains(orders, x[Order]))
in
    z

@luigiPulido_ well, first Table.SelectRows gives you all rows that contain "bbbb" in Product column. Little touch of [Order] after closing bracket gives us a list of order numbers in that table. You may clearly see this list in PQ editor. Then (step z) we filter original tables' orders column. That is all about Table.SelectRows, columns as lists of items, working with lists functions etc.
