How do I use Master Calendar if I have multiple dates? I am trying to build a star schema. I have two different types of dates - OptInDate from Table: Incident and LOA_Date from Table: CloseRate - Screen Shot below. I used the master calendar script twice times. I created two calendars - OptInMasterCalendar and SLOA_MasterCalendar. The OptInMasterCalendar is connected to the Incident table which is correct. But SLOA_MasterCalendar must be connected to CloseRate table. It is currently not. How can I fix this problem. I am pasting the screen shot and the script. I would appreciate your help.
