Match 2 columns from 2 different tables - based on the date and pull the value

[EZiamslow]

Hi,

I'm having trouble matching between two different tables. I'm trying to match between [Date] and [ID] columns from Table1 to Table2 and pull table2[Tool] value. Table2[Date] is equal or 1 day higher than Table1[Date].

Please see the sample data below. I'm not sure what I can do to make it work. Table1[tool] is the one I'm trying to get.

Any inputs will be greatly appreciated.

Table1						(from table2)		Table2
Date	ID	X1	X2	X3	X4	Tool		Date	ID	Tool
7/29/2019	12345	1.2	1.4	1.2	1.1	AA		7/30/2019	12345	AA
7/29/2019	23456	2.0	1.1	1.2	1.5	BB		7/30/2019	23456	BB
7/29/2019	23456	2.8	0.8	1.2	1.9	BB
7/29/2019	53451	3.6	0.5	1.2	2.3	BB		7/30/2019	53451	BB
7/28/2019	34567	4.4	0.2	1.2	2.7	AA		7/29/2019	34567	AA
7/27/2019	23456	2.8	0.8	1.2	1.9	AA		7/27/2019	23456	AA

Hi @Mariusz 

I'm trying to get value Table2[Tool] in Table1. I have it on my sample.

Hi @EZiamslow

Sorry, I've missed that.

You can do it in Query Editor by adding a custom column to the Table1.
Please see the below M code for your column.

let _id = [ID], _date = [Date] in Table.FirstN( Table.Sort( Table.SelectRows( Table2, each [ID] = _id and [Date] >= _date ), { { "Date", Order.Ascending } } ), 1 )[Tool]

Next you will need to expand the list of values.

please see the outcome below.

Let me know if you need any extra help.

Best Regards,
Mariusz

@vivran22  Thanks your DAX code works.

@Mariusz  I haven't tried yours yet. I will try it and get back to you. I'm still learning. It's good to know that we have multiple ways of doing things. Thank you!

Hi @vivran22 

I've tried to look at your solution, but could not find anything in the file, just row tables.
Can you republish the file?

ps. thanks for the kudos!

Hi,

I have checked the link and it is working fine. I am not sure what you are seeing when you are accessing the file. I have suggested the solution using DAX (LookupValue). Below is the screenshot:
