Hello, I am defining new Measures and Dimensions in Advanced settings. Some of my new calculations are based on Custom fields in issues. Some of my calculations did not worked properly, because they could not see Custom Field values. I have found that I have to import all involved custom fields as well, in order to get correct processing of things in Advanced settings. For example, if my calculated Dimension using Language custom field, I have to import Language as well. It is possibly using data previously imported, instead data from JIRA.
This is very inconvenient, as some of those custom fields are needed only in the calculation, so it is just ballast data for the Cube. We are constantly struggling to keep the cube as small as possible, because we have performance issues due to amount of data.
Could you please help me understand the reason behind? Maybe it is bug, maybe it is necessary for something, maybe it is some optimization (working with alredy cached data could be potentially faster)? Is there any workaround? We would prefer longer import time in order to get smaller/faster cube.
