Get the last delivery date

[Grevatious]

Hello everyone

I need help! I have two tables. The first one has all the description of the order and the customer information and the other shows all the information related to the delivery of each order. Each order may have 2 or more tracking numbers with different delivery dates.

What I'm trying to do is get the last delivery date from table 2 for each order in table 1.

I've tried many times in vain, so on the right I'm using the formula "Firstnoblank", but this only returns the first value it finds instead of the last one by date.

Table 2:

Delivery information
Order	Tracking number	Delivery date
123	10001	1/1/2020
124	10002	2/1/2020
125	10003	3/1/2020
126	10004	4/1/2020
125	10005	5/1/2020
123	10006	6/1/2020

Table 1:

Orders
Order	Last delivery date
123	6/1/2020
124	2/1/2020
125	5/1/2020
126	4/1/2020

Thank you all!

Use this measure in you table to display the date

Measure =
VAR __id = MAX( 'Table'[Orders] )
VAR __date = CALCULATE ( MAX( 'Table'[Delivery date] ), ALLSELECTED ( 'Table' ), 'Table'[Orders] = __id )
RETURN CALCULATE ( MAx ( 'Table'[Delivery date] ), VALUES ( 'Table'[Orders] ), 'Table'[Orders] = __id, 'Table'[Delivery date] = __date )

Probably in Table1,

Last delivery date = MAXX(FILTER(RELATEDTABLE('Table2'),'Table2'[Order]=[Order]),[Delivery date])
