Helper ICalculate Previous Months Total
I need to create a measure that documents the previouse months total number of exceptions that were submitted so I can display it in a month on month report. The field for the exceptions, "Combine Exception'[TargetObjectId" is a text so I used the calculate count function. I created a calendar table with a relationship to the date field, "Combine Exception'[CreatedDate ]". But when I add the created date to the formula I am getting an error, "Function "DATEADD' expects a contiguous selection when the date column is not unique, has gaps or it contains time portion."
I have never used a calendar table before so I am not sure if the formual that I have is correct. Below is the formula that I used for my PrevMonth field.
KEO46 , Always used a date table, marked as date tbale joined 1- Many (Single Directional) with your table
PreMonth = CALCULATE(COUNT('Combine Exception'[TargetObjectId ]),DATEADD('Date'[Date],-1,MONTH))

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :radacad sqlbi My Video Series Appreciate your Kudos.
