Circular dependency error in calculated column

[sowjanya123]

Hi,

I need help on resolving circular dependency error :

Below is the calculated column: 

Retro Test Support =

SWITCH(TRUE(),

[FraudPoint LY Revenue]>=100000 && Fraudpoint_Customers[Customer Type Flag]=0,"National Support",

[FraudPoint CY Revenue]>=10000 && Fraudpoint_Customers[Customer Type Flag] = 1,"Strategic Support"

)

FraudPoint LY Revenue is a measure : 

FraudPoint LY Revenue = CALCULATE([Sum of LY Revenue],FILTER(Fraudpoint_Customers,DISTINCTCOUNT(Fraudpoint_Customers[customer_account_sk])))

Sum of LY revenue is also a measure:

Sum of LY Revenue = CALCULATE([Total Revenue], FILTER(ALL('Date'), 'Date'[Closed Revenue Index by Year]=-1))

Total Revenue is also a measure:

Total Revenue = CALCULATE(SUM('fact_revenue_usage'[Total Billed Charges]),FILTER(Customers,DISTINCTCOUNT(Customers[customer_account_sk])))

Looking forward for help on how to fix the circular dependency error coming in Retro Test Support calculated column
