I created a Custom Dimension with simple diff_days()
and then clicked and selected Average
, which created a measure Average of <dim>
. So far so good.
Now I want to change the formatting of that measure. I go and click the gear icon and Edit.
Field to Measure
and Measure Type
are empty
I need to create it in this dialog again. I believe this is something to do with the fact that it is a Custom Dimension
