在两个计算列之间检测到 Power BI DAX 循环依赖

Question

I have a calculated column that works as intended for current year calculations called RTP . For reference here is the code:

RTP = 
VAR ActualPM = AND(AND(
                    'Opex Summary'[Date] >= CALCULATE(STARTOFMONTH('Opex Summary'[Date]),FILTER(ALL(Dates), Dates[Month Offset] = 1)),
                    'Opex Summary'[Date] <= CALCULATE(ENDOFMONTH('Opex Summary'[Date]),FILTER(ALL(Dates), Dates[Month Offset] = 1))
                ),'Opex Summary'[Flag] <> "Budget")
VAR ActualPM_Name = FORMAT(CALCULATE(MIN(Dates[Mth]),FILTER(ALL(Dates),Dates[Month Offset] = 1)) ,"mm/yyyy")

VAR ActualPM1 = AND(AND(
                    'Opex Summary'[Date] >= CALCULATE(STARTOFMONTH('Opex Summary'[Date]),FILTER(ALL(Dates), Dates[Month Offset] = 2)),
                    'Opex Summary'[Date] <= CALCULATE(ENDOFMONTH('Opex Summary'[Date]),FILTER(ALL(Dates), Dates[Month Offset] = 2))
                ),'Opex Summary'[Flag] <> "Budget")  
VAR ActualPM1_Name = FORMAT(CALCULATE(MIN(Dates[Mth]),FILTER(ALL(Dates),Dates[Month Offset] = 2)) ,"mm/yyyy")

VAR ActualPM2 = AND(AND(
                    'Opex Summary'[Date] >= CALCULATE(STARTOFMONTH('Opex Summary'[Date]),FILTER(ALL(Dates), Dates[Month Offset] = 3)),
                    'Opex Summary'[Date] <= CALCULATE(ENDOFMONTH('Opex Summary'[Date]),FILTER(ALL(Dates), Dates[Month Offset] = 3))
                ),'Opex Summary'[Flag] <> "Budget")  
VAR ActualPM2_Name = FORMAT(CALCULATE(MIN(Dates[Mth]),FILTER(ALL(Dates),Dates[Month Offset] = 3)) ,"mm/yyyy")

VAR BudgetPM = AND(AND(
                    'Opex Summary'[Date] >= CALCULATE(STARTOFMONTH('Opex Summary'[Date]),FILTER(ALL(Dates), Dates[Month Offset] = 1)),
                    'Opex Summary'[Date] <= CALCULATE(ENDOFMONTH('Opex Summary'[Date]),FILTER(ALL(Dates), Dates[Month Offset] = 1))
                ),'Opex Summary'[Flag] = "Budget")
VAR BudgetPM_Name = FORMAT(CALCULATE(MIN(Dates[Mth]),FILTER(ALL(Dates),Dates[Month Offset] = 1)) ,"mm/yyyy")

VAR ActualPM_PY = AND(AND(
                    'Opex Summary'[Date] >= CALCULATE(STARTOFMONTH('Opex Summary'[Date]),FILTER(ALL(Dates), Dates[Month Offset] = 13)),
                    'Opex Summary'[Date] <= CALCULATE(ENDOFMONTH('Opex Summary'[Date]),FILTER(ALL(Dates), Dates[Month Offset] = 13))
                ),'Opex Summary'[Flag] <> "Budget")
VAR ActualPM__PYName = FORMAT(CALCULATE(MIN(Dates[Mth]),FILTER(ALL(Dates),Dates[Month Offset] = 13)) ,"mm/yyyy")


RETURN
SWITCH(TRUE(),
    ActualPM, "CY Act (" & ActualPM_Name & ")",
    ActualPM1, "CY Act (" &  ActualPM1_Name & ")",
    ActualPM2, "CY Act (" & ActualPM2_Name & ")",
    BudgetPM, "CY Bud (" & BudgetPM_Name & ")",
    ActualPM_PY, "PY Act (" & ActualPM__PYName & ")",
    "EXCLUDE"
    
)

I am attempting to create a similar year to date calculated column called RTP YTD . This is providing me the following error:

A circular dependency was detected: Opex[RTP YTD], Opex[RTP], Opex[RTP YTD]

The code that creates the error is below:

RTP YTD = 
VAR ActualYTD1 = AND(AND(
                    'Opex Summary'[Date] >= CALCULATE(STARTOFMONTH('Opex Summary'[Date]),FILTER(ALL(Dates), Dates[Month Offset] = 13)),
                    'Opex Summary'[Date] <= CALCULATE(ENDOFMONTH('Opex Summary'[Date]),FILTER(ALL(Dates), Dates[Month Offset] = 1))
                ),'Opex Summary'[Flag] <> "Budget")
VAR ActualYTD_Name1 = FORMAT(CALCULATE(MIN(Dates[Date]),FILTER(ALL(Dates),Dates[Month Offset] = 1)) ,"mm/yyyy")

RETURN
SWITCH(TRUE(),
    ActualYTD1, "YTD Act (" & ActualYTD_Name1 & ")",
    "EXCLUDE"
    
)

I think you need ALLEXCEPT() in your calculated columns. I'd write the code but it is difficult without sample data so you can have a read here:
