Constant Currency dynamic calculation help needed

khaeshr46 — Fri, 13 Oct 2023 06:20:15 GMT

Hi,

I need to create a dynamic Constant exchange calculation for 3 prior years using max rates of the currently selected Quarter Year exchange rates. I have all my sales in Local Currency.

I need to convert the PY Sales LC x 9/30/15 rates for my PY Sales USD(CC)

The mesaure below is giving me the correct CC amount Im looking for in the current slicer selection. How can I modify this to apply for Prior Year Sales LC

Sales USD (CC) =

var ccDate =

Constant Currency Date = CALCULATE(

MAX('FX Rate'[Date]),

ALLSELECTED('Calendar_Lookup'[Date])

)

VAR vSalesWithConstantRate =

SUMMARIZE(

Sales,

'Currency'[Currency],

"_LC Amount",

[Sales LC],

"_Constant Rate",

CALCULATE(

MAX('FX Rate'[Fx Rate to USD]),

FILTER(

ALL('FX Rate'),

'FX Rate'[Date] = ccDate

&& 'FX Rate'[Currency] = SELECTEDVALUE('Currency'[Currency])

)

RETURN

SUMX(vSalesWithConstantRate, [_LC Amount]/[_Constant Rate])

In your situation it is easier (and faster) to use TREATAS to project the filter across the sales and FX tables.

If you like more assistance - please share sample data.

Hi,

Below is some sample data and a new screenshot below of what is required.

PY Sales USD measure is calculating correctly but any suggestion to make the measure perform faster would be appriciated.

PY Sales USD Latest Month Rate is not working.

Also, if I would like to create a PY Full Year Sales USD as well using the selected quarter's exchange rates.

Here is what I have so far. Please have a look at my approach. I guess I don't understand this part:

using max rates of the currently selected Quarter

The measures can be adjusted to the last available FX, for example.

Hi,

The TREATAS works well at row context. But the total was incorrect so i wrapped it in a SUMX SUMMARIZE for Sales USD measure and its giving me the right total. (Sales USD Correct Total)

The PY Sales USD however does not work with SUMX SUMMARIZE. (PY Sales USD Correct Total)

Sorry I was a bit unclear on the "using max rates of the currently selected Quarter" requirement. What I am looking to do is use the max date's FX rates of a selected Quarter. Please see the screenshot below.

Sales USD Correct Total = SUMX(SUMMARIZE('Fact','Fact'[Date],'Fact'[Currency],"A",sum('Fact'[LC Amount])*CALCULATE(max('Currency'[Fx Rate to USD]),TREATAS(values('Fact'[Date]),'Currency'[Date]),treatas(values('Fact'[Currency]),'Currency'[Currency]))),[A])

PY Sales USD Correct Total = SUMX(SUMMARIZE('Fact','Fact'[Date],'Fact'[Currency],"A",[PY Sales LC]*CALCULATE(max('Currency'[Fx Rate to USD]),TREATAS(values('Fact'[Date]),'Currency'[Date]),treatas(values('Fact'[Currency]),'Currency'[Currency]))),[A])

PY Sales USD = var a = summarize('Fact',[Currency],[Date]) var b = ADDCOLUMNS(a,"fx",CALCULATE(max('Currency'[Fx Rate to USD]),TREATAS({[Date]},'Currency'[Date]),treatas({[Currency]},'Currency'[Currency]))) var c = ADDCOLUMNS(b,"p",[PY Sales LC]) return sumx(c,[fx]*[p])

Hi,

Im still struggling to create a new measure that uses the the MAX date's rate depending what the user has selected in the slicer.

I don't see a difference to the other columns.
