I’m always keep an eye open for potential new members of the Barcelona Power BI User Group. When I see a potential candidate I try to connect and get to know him/her. Today I was surprised that one of these unsuspected new members told me he was already using my script for Time Intelligence (yay!) and followed with a question on calc groups (double yay!). He was trying to build a KPI card which used a measure as the main KPI and wanted to use the previous year value as target, and was struggling to apply the calculation group just to the target one. I gave it some thought and I think the final set up might be useful to more people, so here I come.
