How to create time dimension to connect multiple tables
I have a data model where Sales person is connected to multiple entities (Quotations, Contracts etc).
Main idea is to compare how each sales person is doing in relation to the sales team they are part of and how they are doing in comparison to their own history.
I'd like to create a chart that shows count of contracts, count of quotation etc per week. The issues is that I don't have a master calendar as I have connected the entities through users. I tried to create a dimension with ValueList that would "connect" YearWeek values (Q.YearWeek, C.YearWeek). Simply to show different measures in the same graph (e.g. count of quotations created and count of contracts created as lines and YearWeek as dimension).
Any tips or tricks that I could use? Couldn't find anything on my own.. My back up is to make the master calendar and use GetSelectedValues in the measures (select sales person and team). But that doesn't seem too tempting either..
