Get comments from another table in matrix

[yoa380]

Hello,

I have imported in my PBI model a table from Excel where people can put comments.

This fact table 1 has column A = YearWeek in text / column B = Category of products in text / Column C = Comments in text.

I have another fact table 2 with Category of products and some figures

I have a dimension table of products where Category of products is. This table is linked to both Table 1 and 2.

I created a matrix where Line = Category of product from dimension table.

Then matrix values are multiples and comes from measures created in Table 2.

I would like to add as final column of this matrix the comments from Table 1

Can I use a kind of lookup dax formula ?

I always need to show in this comments column = the comment from table 1 for concerned category of product and for yearweek = MIN(yearweek) of another table 3

yearweek is in text in both tables

thanks for quick reply, I don't really need to use my calendar table here as my table 3 (even if several lines) will always only have a single value for YearWeek. I thought using MIN was good idea because I can't just say "equals to YearWeek column".

It's just to make the filter on Table 1.

I tried your logic but I get an error message.

I also tried : 

Comments =

CONCATENATEX(FILTER(Table1,Table1[YearWeek]=MIN(Table3[YearWeek])),Table1[Comments])

It finds my values but it put them all stuck together, without taking into account the Category.

Example for CAT1 it will put = Nothing to declare Trials

Hi @yoa380 

I've tweaked your formula a little bit, and it seems to produce your required output.  

I attach the pbix file as an example.

Hi @yoa380 ,

You can get your required output by using ConcatenateX like below:

I am assuming that your 'Table 1' and 'Table 3' have relationship with the Calendar dimension table.  In order to use the min function, you need to convert "2024W19" to numerical format like 2024.19.  

Best regards,
