incorrect Grand Total

[Anonymous]

My Dax is returning  incorrect Grand Total.  Can anyone help review or rewrite it. 

Demo =
IF (
    HASONEVALUE ( 'Report Currency'[Report Currency] ),
    SUMX (
        'Exchange Rates',
        SUMX (
            'Calendar',
            CALCULATE (
                VALUES ( 'Exchange Rates'[exchange_rate] )
                    * DIVIDE (
                        SUM ( 'Daily Item Sales'[total_amount_home] ),
                        SUM ( 'Daily Item Sales'[qty_sold] )
                    )
            )
        )
    ),
    DIVIDE (
        SUM ( 'Daily Item Sales'[total_amount_home] ),
        SUM ( 'Daily Item Sales'[qty_sold] )
    )
)

Hi @Anonymous 

Brother, would you please place a screenshot of your data model along with the relationships?

The formula contains three tables. Please provide complete information

@Anonymous You might try ISINSCOPE instead of HASONEVALUE. Also, I would create your measure for your rows and then create a separate measure that uses that measure that returns either the row value or the total value depending on whether you are in a row or total row.

First, please vote for this idea: https://ideas.powerbi.com/ideas/idea/?ideaid=082203f1-594f-4ba7-ac87-bb91096c742e

This looks like a measure totals problem. Very common. See my post about it here: https://community.powerbi.com/t5/DAX-Commands-and-Tips/Dealing-with-Measure-Totals/td-p/63376

Also, this Quick Measure, Measure Totals, The Final Word should get you what you need:

@Greg_Deckler  The Isinscope did not help.

@Anonymous Sample data. Sorry, having trouble following, can you post sample data as text and expected output?
Not really enough information to go on, please first check if your issue is a common issue listed here: https://community.powerbi.com/t5/Community-Blog/Before-You-Post-Read-This/ba-p/1116882

Also, please see this post regarding How to Get Your Question Answered Quickly: https://community.powerbi.com/t5/Community-Blog/How-to-Get-Your-Question-Answered-Quickly/ba-p/38490

The most important parts are:
1. Sample data as text, use the table tool in the editing bar
2. Expected output from sample data
3. Explanation in words of how to get from 1. to 2.
