I have a cube which contains a python transform. So it has [input]->[python]->[output].
I need to allow users on the dashboard to filter the cube before the python transform. The python does things to the data, but the columns that I need for the filtering are removed at this stage due to aggregation and similar calculations.
What I have done is do make output parameters on the input transform, and make these public. Is this the right way to do it?
I can’t work out how to access these from the dashboard, as the necessary columns are not in the output transform.
