Calculated average not changing reference

[NotSoPowerUser]

Hello,

I suppose I am still new to Power BI in this forum to perhaps my question is easy for some.

Still I have played with this issue for days now and I cannot seem to solve it desite browsing myself blue in the face.

I got 2 data sets linked through 1 to many ID (Activity ID).

Now, I can sum the revenue in Table 2 by something like below which works fine.

Calculate(Sum(Table2[Revenue]),Filter(Table2,Table2[Activity ID]=Table1[Activity ID])).

However since both tables are being sliced dynamically I cannot actully copy data from table 2 to table 1. 

So I have to use a measure. Now if I plot the average revenue from the above formula I get something completely different reason being the average revenue is reference the product and not the Activity. Not right or wrong I just need it the other way round. 

I have tried a lot of function with SumX, Summarize etc.. I am getting diffent results compared to the alternative fasion using a spreadsheet. I suppose I have learned a lot in the process between tables vs Measures, graphics interface etc. but I am still learning.

Can anway advise please how I make the average Revenue data in a Measure reference the activity..... at least I think that is the issue. 

Kind regards

Alex

Hello,

I managed to figure this our myself. I should have used this forum to start with rather than using a search browser. So thanks to everyone for contributing to this forum.

So to change the calculated average Price per something else I suppose the logic is simple.

Sum all the Prices together in a Calculate(Sum( Table2[Revenue])) then average them out over a different parameter using AverageX(Values('new parameter',Sum) so the total expression will look like this:

AverageX(Values(Table1[Activity],Calculate(Sum( Table2[Revenue])))

Thanks and regards
