BOM Calculation (Circular reference error)

Hi

 

This is a circular referencing Excel example.
This is a sample of costing by rolling up the BOM.
The purchased sub-item E goes into D, and D and C go into B.
Finally, B goes into A.
At this time, the same column F is referenced, but a circular reference error occurs in POWER BI.

No error occurs in Excel.

(check the excel formula)
I want to implement this in Power BI.
How can I do it?

Hi, @HJK 

 

You can try the following methods.
New table:

Table 2 = FILTER(SUMMARIZE('Table','Table'[Parent Item],'Table'[Type]),[Type]<>"Purchase")

Column:

Column = 
Var _N1=CALCULATE(SUM('Table'[Sub Amount]),FILTER('Table',[Parent Item]=EARLIER('Table'[Sub Item])))
Var _N2=CALCULATE(SUM('Table'[Sub Amount]),ALLEXCEPT('Table','Table'[Parent Item],'Table'[Sub Item]))
Return
IF([Type]="Purchase",_N2,IF([Sub Item] in VALUES('Table 2'[Parent Item]),_N1+_N2+_N1,_N1+_N2))

Is this the result you expect?
