Lookupvalue referenced to the its own column

[George1973]

Good evening,

I have excel "Index-Match" formulas which referes (for the result column) its own column, like given in the picture below:

I want to implement this approach in Power Bi calculated column to, but it does not work - I can not refer to the same column where I want to write a mesure..

Simply to say - There is no reference at all for any formula to the same calculating column..

Please help. In excel it's very easy.. but here I've got a "ubreakable wall" 😞

Hi @George1973 
To be honest, I'm trying to guess your expected result. Please try

Tree Leveles New =
IF (
    ISBLANK ( 'Tree of Products'[tree levels] ),
    VAR CurrentParent = 'Tree of Products'[PARENT]
    RETURN
        MAXX (
            FILTER ( 'Tree of Products', 'Tree of Products'[PARENT] = CurrentParent + 1 ),
            'Tree of Products'[product_code]
        ),
    'Tree of Products'[tree levels]
)

Hi Again @tamerj1 
I will try to show you the outcomes in steps through screenshots:
Step 1: Defining the first product group level:

Step 2: Define the second group level

When the Prod_code is now in parent:

Step 3: Define the 3rd level, now the prod_code 022 is in parent:

End so on 🙂

Hi @George1973 
Sorry for the late reply. You can upload the excel to WeTransfer or DropBox and share the link here. I have a feeling that this is one of the recursive calculations that can be solved by dax.
