Advanced filtering in power query - multiple conditions

[zenisekd]

Hi all, 
I bumped into a puzzle that I do not understand...

In power query I have two columns - State (that gives values Cancel, Sales, etc..) and Confirmation Date (gives null or specific date).

I want to filter all rows that contain at the same time Cancel and null. I tried to use Filter Rows - advanced filter and .... it doesnt work. It filters all Cancel and all nulls ... I cant see why... I am not sure about the code, but the logic in the user interface function should clearly work this way, but it doesnt .... or am I missing something?

I managed to find another way to filter the rows, by adding new column and then filtering by it... but I would like to do it in one easy step... not three. Can somebody tell me what is going on?

= Table.SelectRows(#"Added Custom", each [public.sale_order.confirmation_date] <> null and [state] <> "cancel")

Please try this instead

= Table.SelectRows(#"Added Custom", each not ([public.sale_order.confirmation_date] = null and [state] = "cancel"))

You are the boss, sir 🙂 

However, do you think, that the user interface window just doesn't function properly (giving incorrect code), or am I doing something wrong?

Thanks
