Create a table using Distinct values from another table

Anonymous — Wed, 28 Dec 2022 14:59:11 GMT

Let's say I have two tables

ORDERS
--------
Order_Num, Material_Code, etc., etc.,
Ord001, 1001
Ord002, 1002
Ord003, 1003
Ord004, 1003
Ord005, 1001

MATERIALS

-------------

Material_Code, Material_Desc
1001, Blue
1002, Green
1003, Yellow
1004, Red
1005, Pink
etc, etc
etc etc

In reality my MATERIAL table is huge but I need to use Material Description as a slicer but I only want those descriptions showing that are actually in the current ORDER data, meaning each time the ORDER data is refreshed, the slicer should be refreshed. So I decided I needed a dynamic table to feed the slicer and based on the above data it would only contain:

MATERIAL_SLICER
----------------
Material_Code Material_Desc
1001 Blue
1002 Green
1003 Yellow

Now I have tried various DAX such as SUMMARIZE, SUMMARIZECOLUMNS, CALCULATETABLE but I am not getting what I want. If I was to write this in pseudo SQL it would be something like this:

SELECT Material_Code, Material_Desc
FROM Material
WHERE Material_Code in (SELECT DISTINCT Material_Code from Orders)

What is the similar DAX syntax?

hi Anonymous

try like:

SlicerTable =

SUMMARIZE(

Orders,

Materials[Material_Code],

Materials[Material_Desc]

)

Thanks but unfortunately not the solution. The way I understand the SUMMARIZE function is that it can only summarize on a field in its own dataset.

This works: slicerTable = SUMMARIZE(Orders,Orders[Materials_Code]) and returns the distinct list of codes (but no descriptions of course).

slicerTable =SUMMARIZE(Orders,Orders[Material_Code], Materials[Materials_Desc] )

fails with "The column 'Material_Desc' specified in the 'SUMMARIZE' function was not found in the input table." and any variation that puts a column from Materials in the query, fails with a similar message so your suggestion:

SlicerTable =

SUMMARIZE(

Orders,

Materials[Material_Code],

Materials[Material_Desc]

)

crashes with a similar message.

I think I may have to do multiple steps!

Hi Anonymous ,

Please try:

Table = FILTER('MATERIALS',[Material_Code] in VALUES(ORDERS[ Material_Code]))

Final output:
