Hi @admin11 ,

I think you can try to get correct subtotal by SUMX() based on [_YTD_GPM] measure.

Measure 7 = SUMX(VALUES('DATE'[YrMth Sort]),[_YTD_GPM])

PnL CY = SWITCH(SELECTEDVALUE('_PnL_Var'[PnL_Var]),
                            "1_REV", [_YTD_REV_N],
                            "2_COGS",[_YTD_COGS1],
                            "3_OTH", [_YTD_OTH_IN],
                            "4_EXP", [_YTD_EXP2],
                            "5_NET_P",[_YTD_NP_],
                            "6_GPM",[Measure 7],
                            "7_NPM",[_YTD_NPM]
                            )

Result is as below.

Thank you very much for your response.

i Have found out the issue :-

_YTD_GPM_ = DIVIDE([AMOUNT_REV_N]+[AMOUNT_COGS],[AMOUNT_REV_N])

But i go and use :-

_YTD_GPM = DIVIDE([_YTD_REV_N]+[_YTD_COGS]+[_YTD_OTH_IN],[_YTD_REV_N])

So it cause the problem.

As SUMX usually solve Overtotal problem.

Any way thank you very much.
