Dax - create a calculated column referencing a measure

I have a measure (Change %) giving me the % decrease/increase by year from a series of values in the Production table.

 

I want to calculate the average decline but only when the Change % is positive.

 

I think I need to create a Yes/No flag in the Production table to toddle on/off for this to work but I'm open to options.

 

Thanks

I understand you're trying to calculate the average decline but only for the years when the Change % is positive. You're right that one way to approach this is by creating a calculated column to flag the rows where the Change % is positive.

First, you'd create a calculated column in the Production table. Let's call it "PositiveChangeFlag". The formula for this column would be something like:

PositiveChangeFlag = IF([Change %] > 0, "Yes", "No")
This will give you a "Yes" for rows where the Change % is positive and "No" otherwise.

Now, to calculate the average decline for only those years with a positive Change %, you'd create a new measure. Let's call it "Avg Positive Change". The formula would be something like:

Avg Positive Change = CALCULATE(AVERAGE(Production[Change %]), Production[PositiveChangeFlag] = "Yes")
This measure will give you the average of the Change % but only for the rows where the PositiveChangeFlag is "Yes".
