Measure gives wrong total values

[Anonymous]

I have 2 tables with data, for which I want to match the totals of Data B when the row on Data A is > 0. The measure I figured would work, only works on row level, but not on totals.

Measure= IF(SUMX(Data A;Data A[Values]) > 0;SUMX(Data B;Data B[Values]))

Result 24.496, expected value 19.054.

Why does this happen, what am I missing here? Ideally I'd just "SUMIF" on date and itemID from A to match values with B, but I couldnt find an Excel equivalent for DAX that worked for me.

Perhaps a calculated column would probably be better, but both datasets are detailed differently. Is there perhaps a way to create a new table, totaling on itemID + date from both tables (ideally with Data A being the generator of the itemID's)?

Just going to bump this topic one time in hopes of a solution, otherwise I'll probably have to try and fix it in SQL instead.

Could this be considered a bug, or is this the subtotal a result of me using the wrong formula?

@amitchandak When I use your measure, I have 2 options for the itemID. The one from data A or my table that links the 2 itemid's together. However, both seem to do the same thing in the totals:

Using the ItemID-link table:

Using the ItemID from table A:

EDIT: In case it is important to mention, there are other filters on this page (date/category). I do get different results if I change the category or remove it completely, but the results act in the same way.

@Anonymous , Try measure like

Measure= Sumx(values(Table[Item ID]) IF(SUM(Data A[Values]) > 0;SUM(Data B[Values]), blank()))

use correct table for item id
