Delayed month end

[Anonymous]

Folks: 

I am a big fan of the Relative Date Slicer in Power BI.  Financially - we report monthly.  The majority of my reports use a Last 36 Months (Calendar) - and this works great.  As I write this - my slice is 3/1/2016 - 2/28/2019.  Just what I want. 

My problem is - that window will change with the calendar.   On the first of April - the dates the slicer uses will be 4/1/2016 - 3/31/2019.  We have a processing cycle that takes about three or four business days to complete.   So the calendar may say it is April - but that does not inply we are done with March.  We typically are not ready for this switch until the 6th or 7th.

I can write a DAX function that would know the last certified date.  I can also put a certified attribute on my Date dimension. 

Does anyone have any ideas on how I can delay the transition?

@Anonymous I think you can achieve this by adding new colum in date dimension for "Month Offset" whcih will use certify date and then use that offset column to see last 6 months data. You will not require relative date filtering in that case.

Assuming you have table called certified date and add following new column in your date dimension.

Month Offset = 
VAR __cDate = MAX( 'Certified Date'[Certified Date] )
VAR __date = IF( ISBLANK( __cDate ), TODAY(), __cDate )
RETURN
DateDiff( __date, 'Date'[Date], month )

And on filter you can use something like this, you can make changes as per your need, but it give you an idea how you can use own relative filtering instead of in-built relative date filtering.
