Conditional Decomposition Tree

[cirooric]

Hello, I have a dataset of two products classes, "CARPENTRY" and "OXICUT".

Every CARPENTRY code is divided by "Process", "Machineries" and "Material", while every OXICUT code is divided by "Thickness" and "Process".

I would like to represent this division with a decomposition tree where the first level is the "Class" and then, based on the chosen class, the other levels will show.

I had a table of the CARPENTRY codes and a table of the OXICUT codes as shown below:

CARPENTRY Table       OXICUT Table

So i merged them in power query, obtaining the TOTAL table:

TOTAL Table

I've tried to put in the "Explain by" fields all the columns but i don't know ho to display the respective column based on the chosen class.

Hi  @cirooric ,

You might consider using Append in Power Query.

Merge is different from Append in that Merger allows you to select different types of joins to combine two or more queries by matching values in specified columns.

The Append approach, however, aggregates the column headings of Table A and Table B to create a new table, appending the rows of Table B to the end of Table A, so that after Append, the data in Table A and Table B are .

Two different ones:

In power query – Home – Merge Queries -- Merge Queries as new.

Using the Append table's [Class] as a slicer and placing the data you want to get into the matrix, you can realize which Class is selected to display the corresponding hierarchy.
