How to combine TOP 6 & BOTTOM 2 results from another DAX measure into new measure

Ilias_pal — Sat, 17 Sep 2022 16:43:59 GMT

I have linked SAP with PowerBI two different tables, one containing current year sales per product & country and the other containing previous year sales per product & country.

I have created a DAX measure to calculate "vs. Prior Year" sales and now I have been asked to create a chart that will show the top 6 and bottom 2 products, so each country lead can get this info.

I am trying to filter in the chart of "vs. Prior Year" both Top 6 and Bottom 2 filter, but it`s not allowing.

Also, i am trying to use a new DAX measure that will combine Top 6 & bottom 2 "vs. Prior Year", however TOPN measure requires a table in the 2nd position and it doesn`t accept another DAX measure

TOPN(<N_Value>, <Table>, <OrderBy_Expression>, [<Order>[, <OrderBy_Expression>, [<Order>]]…])

Any idea how I can solve this?

Thank you in advance.

Hi Ilias_pal

i don't have enough information to generate dax code that serves your requirement but I can give you an idea on how to proceed.
So my understanding is that your chart will slice the [Sales Amount] measure by product leaving a country slicer on the side. The way to move forward is create a filter measure and place it in tge filter pane of the visual.
The measure shall be based on a virtual table that UNION the TOPN - 6 - DESC and TOPN - 2 - ASC of ALLSELECTED products then checks IF the CrrentProduct is within these products and if so returns a fixed value otherwise returns blank.
This way you can filter the chart by selecting "Is not blank" for this filter measure.

Hi tamerj1 ,

This is the first DAX measure, I have created which calculates the "vs. PY Net Sales"

The Current Year Net Sales are sourced from the table "CV_BPC_BRIDGES_R4_FC", while the Prior Year Net Sales were already calculated in the " PY Actual Net Sales' that is included in the measure and are sourced from the table "CV_BPC_BRIDGES_R4_ACT"

As you correctly mentioned, the country selection will be through a slicer, however since the two tables "CV_BPC_BRIDGES_R4_FC" & CV_BPC_BRIDGES_R4_ACT" do not contain similar rows, it`s not possible to use UNION measure.

Do you have any other idea how I can create a measure which will show me dynamically the top 6 and bottom 2 products "vs. PY Net Sales" measure so I can visualize it like this?

Thank you very much in advance.

What is the name of the prduct name column that is used in the chart and from which table?

Hi tamerj1 ,

It`s called "Brand" from product list table.

Product list table and the other two tables above, are linked with relationship 1 to many (1 brand can be many times in the other two tables)

Hi Ilias_pal

Please place the following measure in the filter pane of the chart, select "is not blnak" and apply the filter.

FilterMeasure = VAR CurrentBrand = SELECTEDVALUE ( 'Product List'[Brand] ) VAR T1 = ADDCOLUMNS ( ALLSELECTED ( 'Product List'[Brand] ), "@PYSales", [vs. PY Net Sales] ) VAR Top6 = TOPN ( 6, T1, [@PYSales] ) VAR Bottom2 = TOPN ( 2, T1, [@PYSales], ASC ) VAR T2 = SELECTCOLUMNS ( UNION ( Top6, Bottom2 ), "@Brand", [Brand] ) RETURN IF ( CurrentBrand IN T2, 1 )
