Sum multiple columns from multiple tables? How to?

This is the last part of a large custom report.   I've created two measures and a caluculated column:   1. New Customer Points Per Dollar = CALCULATE(ROUNDUP( SUM('SALES DETAILS'[Sales Line Sales...

    heathernicole just add the 3 Measures into a new one (or 2 Measures and 1 SUM(Column))

     

    EDIT: as to kcantor point about the Relationship View - we just need to see the tables involved in this calculation and the columns connecting them

    Speaking to the extra 2000:  Unlike in excel, PowerPivot and PowerBI calculate each 'cell's' individual total based upon the calculations. Each cell is an island so to speak. While it may only show up once in your visual, within the calculation itself it must appear more than one time. There is a reference card that helps with this issue and it can be found here:

    As for your data model . . . wow. Do you need all of those tables for this particular use? I only ask because a coworker of mine tried to use one data model for everything and it slowed it down to a crawl. A smaller, more nimble datamodel can quickly be created for many projects. She had about 10 fact tables and no lookup tables.

    How many actual tables are you using from this diagram for this partiular project and have you dropped any columns you don't need to reduce size?

    In general, I have 4 lookup tables that I match to most fact tables. My largest model uses 5 fact tables but I keep the column count as low as possible to reduce size and calculation time. Also, are you populating your rows from a lookup table or from a fact table? Using a fact table as row values can cause many issues and play Mary Hobb with your numbers.

    heathernicole Obiviously your Bonus Points Measure is the Problem...

     

    In the bottom total row it defaults to the value between 25000 and 49999 because thats the total in the bottom row

     

    Therefore you need to convert it to a Calculated Column instead of a Measure (use same formula)

     

    Then create a Measure that will sum that Column and then add all 3...

    Looking at the screen captures it appears that the grand total is recalculating the bonus points total based upon the grand totals of the other columns. You can either swich to a calculated column or look at using a much longer workaround.

    this will also affect subtotals.

    Edit: Looks like Sean beat me to that one. :)

    last ditch effort here:

    Go back to the original measure that worked correctly in the row but not in the grand total. Apply the 'fix' from this blog post to correct how the total is calculating.

    http://www.powerpivotpro.com/2012/03/subtotals-and-grand-totals-that-add-up-correctly/

    The problem is only the grand total as it meets the other critera for raising points. If you correct it to calculate differenlty it should solve the issue.

    heathernicole  I created this sample data to hopefully resemble what you are working with

    The 3 Tables are related this way

    Try the formula highlighted in the image below

    It worked for me! I hope it works for you too! Let me know...
