Avoid circular dependency error by using previous

[Satya2804]

Below is a sample data - first 3 columns are my inputs. Total Supply, Match and Long are my calculated columns. 

Total Supply = Current Quarter Supply + Previous quarter Long. Example Total Supply Q2 = 38 + 6 = 44

Match = Min(Outlook, Total Supply). Example Match Q2 = Min (41, 44) = 41

Long = Total Supply - Match. Example Long Q2 = 44-41 = 3

PowerBI gives a circular dependency error but Total Supply is actually using previous quarter Long and not current quarter long, so logically it is not circular. 

Can anyone help replicate the measures in PowerBI?

Quarter	Supply	Outlook	Total Supply	Match	Long
Q1	31	25	31	25	6
Q2	38	41	44	41	3
Q3	42	22	45	22	23
Q4	45	22	68	22	46

HI @Satya2804,

I'd like to suggest you repalce these calculated columns to measure formulas with these calculations.

When you use calculated column to loop refence between different columns, they may case the circular dependency due to the conflict of internal relationships mapping and references.

You can look at the following blog to know more about this issue:
