In my chart, I calculate a measure. Let's say the calculated measure name is 'Difference' which is populated using the variable v_diff.
Now I want to set flags based on the value of 'Difference'.
I create a new dimension named 'Flag' and put the expression as follows.
if($(v_diff) > 1000, 'Yes','No'). When I complete this, I get the result as invalid dimension. But it works if I define it as measure. Unfortuantely, I want it as only dmension so that I can filter based on the value of 'Flag'.
