DAX HELP

Hi, Anonymous 

I am unable to access the link. For further information, please show us a valid link. So I create data to reproduce your scenario.

TableA:

TableB:

There is a many-to-one relationship between two tables.

You may create a measure as follows.

SumQuantity = 
var _result = 
SUMX(
    RELATEDTABLE(TableB),
    TableB[Quantity]
   ) 
return
IF(
   _result= 0,
   0,
   _result

)

Result:

Best Regards

Allan
