grouping, sorting and a drop down list

[baBI123]

Hello, I am new to power BI and I need help with a small project. What I have is on the left and what the desired outcome is on the right (see picture)

I have part numbers and I want to know the following information for each part number: 
the total qauntity ordered (I want the sum of the data), total cost (sum of data), and finally I want a drop down list that will show me all the PO #'s that go along with that particular part number. 
Does this make sense??

Thanks in advance!

Hi @baBI123,

It is not possible to add a drop down list as a table column. As a workaround, you could list all "PO#" inside a single cell for each part number. Please create a calculated table using below formula:

SummarizePO =
SUMMARIZE (
    'PO Table',
    'PO Table'[Part Number],
    "Total Cost", SUM ( 'PO Table'[Total Cost] ),
    "Quantity Ordered", SUM ( 'PO Table'[Quantity Ordered] ),
    "PO list", CONCATENATEX ( 'PO Table', 'PO Table'[PO#], "," )
)

Best regards,

Yuliana Gu

@Phil_Seamark do you think you can take a look at this? It has to do with the other answer you gave me, but now I am trying to build on that...
