Sum a colum if the key is present on another table DAX

Hello everyone,


I have an item table:

item_id   price

01           5

02          10

03            7


And I have an event table:

event_id     item_id

grty           02

bfgz          03

fdbx          03

azrq          02


One item can be affected by multiple events.


I would like to have a measure that will sum the total price of all items that are present in the event table.

In this example, that would be item 02 and 03. Therefore the total price would be 17.


Can anyone kindly help me with this DAX problem?


Thanks in advance,

Lucas

@lucasrm , Try one of the two. if first one joined

 

calculate(sum(Table[price]), filter(event, not(isblank(event[item_id]))))

 

or

 

calculate(sum(Table[price]), filter(Table, Table[item_id] in allselected(event[item_id])))

@lucasrm in this case first you need to create a relationship between two tables like below

Hello @negi007 !

Thanks for the help but unfortunately that was not what I was looking for. I had already the two tables linked. I actually needed a measure so I could calculate totals and etc.

 

I took your pbix file and used the DAX from @amitchandak and it worked!

Here's the result I was looking for:

Thanks @amitchandak , it worked great!

I tried something similar before but I was afraid that this type of DAX would sum repeatedly the price for each occurence of item in the event table. I was wrong, it worked perfectly!
