Record numbering - by category and ascending

[Sebastian_Dudek]

Good morning,

I want to create a column "order" which will be responsible for:

I have a table of transactions. Each transaction has its owner ("owner" column) and the date of transaction ("date_tran" column).

What I want to receive is this:
The "order" column tells us which order is the transaction for the given owner.

Example.

Owner: XX , date_tran: 2020-01-02 , order: 1
Owner: XX , date_tran: 2020-03-02 , order: 2
Owner: XX , date_tran: 2020-05-02 , order: 3
Owner: XXWW , date_tran: 2020-01-02 , order: 1
Owner: XXWW , date_tran: 2020-03-02 , order: 2
Owner: XXWW , date_tran: 2020-05-02 , order: 3
Owner: XCX , date_tran: 2020-01-02 , order: 1
Owner: XCX , date_tran: 2020-03-02 , order: 2
Owner: XCX , date_tran: 2020-05-02 , order: 3

Thank you for your help!

@Sebastian_Dudek - Seems like an implementation of Cthulhu - https://community.powerbi.com/t5/Quick-Measures-Gallery/Cthulhu/m-p/509739#M211

It's a repeating counter with criteria for restarting the counting.

Or maybe ranking will work. https://community.powerbi.com/t5/Quick-Measures-Gallery/To-Bleep-with-RANKX/m-p/1042520#M452
