Recursive calculation in table using DAX

[Cipriano]

Good afternoon everyone,

To request your support, I am starting in Power BI, and I need to perform the calculation of the column: consumptionCalculated, this value is calculated:

1.- When the father does not have a value in the column: consumption and its value is dependent on the consumption of its children. For example:

consumoCalculado de PadreA = consumo Hijo1dePadreA + consumo Hijo2dePadreB

consumoCalculado de PadreA = 200 + 300

consumoCalculado de PadreA = 500

2.- When the parent or children have a value in the column: consumption,

consumoCalculado de PadreC = consumo

consumoCalculado de PadreC = 100

consumoCalculado de Hijo1dePadreB = consumo

consumoCalculado de Hijo1dePadreB = 100

La tabla de datos de ejemplo:

clavePadre	clave	nombre	consumo	inventario	saldo	consumoCalculado
	cve001	PadreA		1000	800	500
	cve004	PadreB				200
	cve007	PadreC	100	600	500	100
cve001	cve002	Hijo1dePadreA	200			200
cve001	cvd003	Hijo2dePadreA	300			300
cve004	cve005	Hijo1dePadreB	100	200	100	100
cve004	cve006	Hijo2dePadreB	100	300	200	100

In advance, I thank you for your valuable support.

Greetings, Cipriano.

Hi @Cipriano ,

Please try this code to create a calcualted column.

consumoCalculado = 
VAR _Child =
    SUMMARIZE (
        FILTER (
            'Table',
            'Table'[nombre] <> EARLIER ( 'Table'[nombre] )
                && CONTAINSSTRING ( 'Table'[nombre], EARLIER ( 'Table'[nombre] ) )
        ),
        [nombre]
    )
VAR _SUMCHILD =
    CALCULATE (
        SUM ( 'Table'[consumo] ),
        FILTER ( 'Table', 'Table'[nombre] IN _Child )
    )
RETURN
    IF ( 'Table'[consumo] <> BLANK (), 'Table'[consumo], _SUMCHILD )

Result is as below.

Will you have situations in your data where PadreC does not have any child records?
