Help with Count based on another column

[Anonymous]

I have an example data set:

ID	Type	Quantity
1	IP	1
2	IP	1
2	OP	7
3	IP	1

I want to sum the  Quantity of OP types where the unique IDs have an IP and OP Line item. IE we would only sum ID 2 which would equal 7. What Dax measure could I create to do this?

How about this?

OP with IP =
VAR CalcTable =
    ADDCOLUMNS (
        VALUES ( Table01[ID] ),
        "@HasIP", "IP" IN CALCULATETABLE ( VALUES ( Table01[Type] ) ),
        "@QtyOP", CALCULATE ( SUM ( Table01[Quantity] ), Table01[Type] = "OP" )
    )
RETURN
    SUMX ( FILTER ( CalcTable, [@HasIP] ), [@QtyOP] )

Hi @Anonymous,

Depends on what you want to happen to the IP type rows.

Something like this?

[measure] =
CALCULATE (
    SUM ( Table[Quantity] ),
    Table[Type] = "OP"
)

I want to ignore the IP rows, but sub the OP rows in whihc the ID was also associated with IP 

[KNP]

Not sure I completely follow.

Does the measure I provided do that?

NO this will some all IDs that are OP, I want to some IDs that were IP but now OP.

I think I got what you're after with my answer but it would help to include in your sample data rows that distinguish between just summing OP and summing OP that were previously IP. These are identical with your given example.

ID	Type	Quantity
1	IP	1
2	IP	1
2	OP	7
3	OP	1
4	OP	8

So in this example we owuld only want to sum ID 2, bc its the only one that was previously IP

[AlexisOlson]

Yeah, I got it. I'd recommend editing that into your original post though.

The DAX I suggested should work fine for this example.
