Need Help! Creating multiple DAX measures

Hi ! Really appreciate your help in this.. Have been stuck for 3 days.. 

 

TableA: 100,000 rows

VersionPartNoRefNoTypePartQty
V1A1233532-421X5
V1B2345754-643Y3
V2C3424362-346X2
V2A3526853-435Z6

 

TableB: 200,000 rows

SupportingPartNoRefNoPeriodRefQty
P0043532-421M1100
P0056853-435M1200
P0046853-435M250
P0064362-346M3400

 

I would like to create a measure UseQty.

UseQty = RefQty * PartQty when RefNo (in Table B)= RefNo (in Table A)

Eventually I would like to create charts using Period (Table B), PartNo (Table A), Type(Table A) and UseQty (Measure) for a given Version.

 

I tried creating an additional column in Table B via PowerQuery but that ended up making the calculation very slow as I have 100k rows in Table A and 200k rows in Table B. 

 

I tried creating a table measure and I ended up having 3Million rows

UseQty = GENERATEALL(
TableA,
var Ref = A[RefNo]
RETURN
SELECTCOLUMNS(CALCULATETABLE(TableB, TableB[RefNo]=Ref),"PartNo",TableB[SupportingPartNo],"AttachRate",TableB[RefQty], "RequiredQty", TableB[RefQty]*TableA[PartQty])
)

 

Is there a way to create measures instead of tables?

Hi, @learner4eva ;

You could try to create a measure  as follows:

Measure = 
CALCULATE( MAX('TableA'[PartQty]),FILTER('TableA',[RefNo]=MAX('TableB'[RefNo])))*MAX('TableB'[RefQty])

The final output is shown below:

@learner4eva , You need to create a common dimension refno

 

RefNo = distinct(Union(all(Table[RefNo]) ,all(Table[RefNo]) )) //or use distinct in place of all

 

example

Bridge Table: https://www.youtube.com/watch?v=Bkf35Roman8&list=PLPaNVDMhUXGaaqV92SBD5X2hk3TMNlHhb&index=19

 

 

Then create a measure like

sumx(Values(RefNo[RefNo]) , calculate( sum(RefQty]) * sum(PartQty) ) )

 

 

if you want a new column way
