Time analysis in Paginated reports

[wfreeman]

I am looking for a little help creating a paginated report.  I am doing analyitics on police activity, looking to show percentage of change between a selected month and the month prior.  I would like one column to represent current value, and have second column represent month prior and ideally a third column showing the percentage of change.   Anyone have any suggestions??  Thank you!!

Thank you again for the help!  It did work for getting the data that I wanted!  It worked with just using some tables from my SQL database, but if I try to use my live connection SQL Analysis I get an error trying to connect to the power bi report using paginated report builder.  Once I have published the report to the service, i use a gateway to connect to our data.  This is error I am getting if you have any solutions.....

Thank you for the reply.  My data model does contain a date table already, do I need to still add the date table in your example?

Hi @wfreeman 

Here I build a date table is to show you that you need a continuous date table to use time intelligence function like "PREVIOUMONTH" in your report. If you already have a related date table with continuous date, you can use this one directly. If the dates in your date table aren't continuous, build a date table by my way.

For reference: Get the DAX query for the dataset

Hi @wfreeman 

I build a sample for you, you may refer to the data model and code in this sample.

Calendar table:

Calendar =
VAR _T1 =
    ADDCOLUMNS (
        CALENDARAUTO (),
        "Year", YEAR ( [Date] ),
        "Month", MONTH ( [Date] ),
        "YearMonth",
            YEAR ( [Date] ) * 100
                + MONTH ( [Date] )
    )
VAR _T2 =
    ADDCOLUMNS ( _T1, "RANK", RANKX ( _T1, [YearMonth],, ASC, DENSE ) )
RETURN
    _T2

Relate Date column with Date column in your Fact table.

Measures:

Last Month Value = 
CALCULATE(SUM('Table'[Value]),PREVIOUSMONTH('Calendar'[Date]))

Change Percentage = 
VAR _Change = SUM('Table'[Value]) - [Last Month Value]
RETURN
DIVIDE(_Change,[Last Month Value])

Result is as below.

You may refer to this blog to build measures in Paginated reports.
