Sum column values by same row value

[PaulPed4]

Hi there,

I have a table which reflects my itemised sales data and includes the following:

• Order Number
• Item Code
• Item Description
• Qty
• Total Sale

The same order number can be present on multiple rows as it would be a single order for multiple items. I want to create a calculated column that sums all of the Total Sales values by Order Number, to give me a total sale by Order Number value.

What is the DAX for this?

Thanks.

Hi @PaulPed4,

Based on my test, you could refer to below steps:

Sample data:

Create below measure:

Measure = CALCULATE(SUM(Table1[Total Sales]),FILTER(ALL('Table1'),'Table1'[Order Number]=MAX('Table1'[Order Number])))

Result:

You could also download the pbix file to have a view.

Hi Daniel,

I found the error I made, there was a single ")" I missed in the formlua which was difficult to spot...

However, I found that the correct formula was in fact to use EARLIER and not MAX.

Thanks,

Now I have a different issue but related to the same source formula.

Now that I have the correct sum of the line items per PO, I need to get an average of those totals. When I place the field in a Card and specify for it to be presented as an average, it gives me an incorrect answer. When I export the table with PO numbers and totals for those POs I get the correct average which is lower than the Card.

Now if I create the below Measure the average is calculated correctly. Why?

Average PO Spend = AVERAGEX(SUMMARIZE(Table, Table[PO], "to Average", [Spend Measure]), [Spend Measure])

Spend Measure = CALCULATE([Total Spend], FILTER(Table, Table[PO]))

Hi Daniel,

I used your formula but PBI is giving me an error stating there are too few arguments for the FILTER function and it requires a minimum of 2?

Remembering that I need this to be a New Column and not a Measure, would that make a difference with the formula required?

Sorry, still very new to DAX and trying to get my head around it all.

Thanks,

Paul

Hi @PaulPed4,

Could you please offer me a sample file and post your desired result if possible? So I could test for your desied result.

Hi,

In your Table visual, drag Order Number and write this measure

=SUM(Data[Total Sale])

Hope this helps.
