Setting Dynamic End Date - Using M Query

Hello Everyone!
I want to create a Calender Table using M query, I used the following code:

as in my Condition The Start Date must start from 1st of May, and ends on 30th April as the working dates of the client.

I hardcoded the start date as 2018/5/1 according to data given by the client.

 

but I want to make the end date dynamic respective to my data model data, and want to auto increase the end date according to data in data model. 

Kindly help!

 

 

 

 

let
     StartDate = #date(2015, 5, 1),
    EndDate = #date(2050, 4, 30),
    //Used for 'Offset' Column calculations, you may Hard code CurrentDate for testing e.g. #date(2017,9,1)
    CurrentDate = if PretendCurrentDate = null 
                    then DateTime.Date(DateTime.FixedLocalNow())
                    else PretendCurrentDate,
    // Specify the last month in your Fiscal Year, e.g. if June is the last month of your Fiscal Year, specify 6

Hi

instead of hardcoding the end date, you can replace it by a reference to the date column from your fact table(s):

 

Date.EndOfYear(

    List.Max(YourFactTable[DateColumn])
)

 

If there are multiple fact tables that could contain the max value, you can concatanate their date-columns like so:

 

List.Max ( YourFactTable1[DateColumn] & YourFactTable2[DateColumn] & YourFactTable3[DateColumn] )

Hi,

 

The Date.EndofYear = EndDate? in MQuery?

I want to show forecast revenue and compare it with actual in the same date context from my Calender table.

 how to achieve that?

Example Expected Result Required.

 

Consider date 15/March/2020 as my Current Date

 

Kindly Help how can I create this kinda measure to show forecast values as per the above requirements.
