Summarize values by category across 2 fact tables

[parimal]

I have two fact tables  -

Fact1 (CustomerID, ProductID, DateKey, Value1) , Fact2 (CustomerID, ProductID,DateKey,Value2)

I'm trying to get a summarized table that gives me 

Summary Table = CustomerID, ProductID, DateKey, Sum(Value1), Sum(Value2)

I tried using the Summarize function, but it doesn't work.

If I do SUMMARIZE on Fact1, I get the Sum(Value1)  but Sum(Value2) is blank. If I do SUMMARIZE on Fact2 , the Sum(Value1) is blank.

The two FACTS are both related to a Customer, Product & Date Dim table. But there's no direct relationship between them. 

I tried creating a KEY column in both FACT tables and do a USERELATIONSHIP, that didn't work either. 

Appreciate any guidance to resolve this ..

hi @parimal 

for example

Table = 
AddColumns(
SUMMARIZE(Fact1, Fact1[CustomerID], Fact1[ProductID], Fact1[DateKey], "Sum1", SUM(Fact1[Value1])),
"Sum2", CALCULATE(SUM(Fact2[Value2]), FILTER(ALL(Fact2), Fact2[CustomerID]=[CustomerID] && Fact2[ProductID]=[ProductID] && Fact2[DateKey]=[DateKey]))
)

Superb.. Thanks a lot. This worked.. 

I was trying a similar statement for a long time, but I was doing FILTER(Fact2, .... ) , whereas you did a FILTER(ALL(FACT2)... )

putting the ALL made all the difference.. , any idea why it might not have been working without the ALL ??

HI @parimal 

without ALL() the statement enables row context (filters depending on your data model). ALL() give a confidence that all table is being calculated
