Create a Summary Data Table with Basic Math Functions

[Anonymous]

I have data source that contains thousands of Sales Orders. Each Sales Order can have multiple lines on the order, so most of the data is the same across each row. However, there are a few differences and I would like to create a summary table that essentially rolls-up certain information for each unique Sales Order #. 

Here is a very simple example of what I am looking to do.

When all is said and done I will have multiple columns that I will be performing basic math on, but I'd hope if I can do it for one, it will be easy to replicate. 

Can anyone help me out?

you can try group by in pq

or use DAX to create a new table

Table 2 = SUMMARIZE('Table','Table'[sales order],"cost",sum('Table'[cost]))

Thank you! Is there a way I can also create a column that counts how many lines were essentially rolled u? In this case 3 for each.

try this in PQ

Table 2 = SUMMARIZE('Table','Table'[sales order],"cost",sum('Table'[cost],"count",COUNTROWS('Table'))

or try this to use DAX to create a table
