Thank you for your reply.
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?
