Sum multiple columns from multiple tables? How to?
- 10 years ago
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.

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...
Create a measure that adds them together then sort by your sales rep on the rows.
Total Points = [New Customer Points Per Dollar] + [New Customer Pts] + [Bonus Points]
Your measures are coming from different tables but should still total up in the new measure. Measures are portable that way.
That's exactly what I went for first. :)
Here's what I end up getting:
Full Error Message:
A single value for column 'New Customer Pts' in table 'Customer' cannot be determined. This can happen when a measure formula refers to a column that contains many values without specifying an aggregation such as min, max, count, or sum to get a single result.
So then I tried a calculated column - get the same error. I'm not sure what it means exactly...

It seems you are adding 2 Measures and a Column! You can't do that.
Add a SUM(...) before the column name
Edit: Or create a measure that SUMs that column and substitute it in the formula
Edit2: And verify you are getting the right answers since you are using multiple tables (just noticed)
if the filters propagate correctly based on the relationships you've set?

Neither of those is working properly... :(
Just to sum that one column doesn't work. It seems to be the Bonus Points that messes up the equation when it comes to filtering.
The relationships are there. This seems like basic math... you'd think this was relatively simple... :(

Here's what I get without adding the bonus points...
Then if I add the bonus points it splits it for some reason...
I'm not sure where to go from here on this one.
In reality it should just put a numeric value against the New Customer Pts per Dollar column... if it's over 10,000 - put 2,000, if it's not - it should leave it alone... not split everything.

It looks like you are missing a relationship. You may need a bridge table. Can you provide us with a screenshot of your datamodel diagram?
