Calculate Task Backlog

[Anonymous]

Hi,
This might be a simple one but I am stuck in this.

I have a Power BI table with Ticket IDs, Created Date, completed date, Ticket Status
The ticket which are closed, have a completed date and which are in backlog has 1st, December, 3799 mentioned.
The tickets also have "Status Column" - Cancelled, Completed, On-Hold, Backlog.
I have already summarized the counts in power BI as attached in the Image

Summary Table name is "Ticket Summary".
I do not have any Dates / Calender Auto table but can create one if needed.
What I want to achieve now is calculate the Backlog as highlighted in the Image
I can only use DAX functions as the data is on another tenant whose credentials I don't have.
All the help will be appreciated.

Regards!!

Hi @Anonymous 

I had solved it using Index column and "Earlier" Function but could not post the solution on time due to work.

What I did was to create index column using 

Index = RANKX( ALL(Table_Name), Table_Name[Month_Year], , ASC, Dense)

Then calculated the backlog for individual month - i.e. MonthlyBacklog = Total_Cleared - Submitted

Then created column :

Cumulative Backlog=

SUMX(FILTER(Table_Name,Table_Name[Index]<=EARLIER(Table_Name[Index])),Table_Name[MonthlyBacklog])

But your solution works better as there won't be a need to create additional column "MonthlyBacklog" as I did. 
PS: Apologies for not posting the question in a better way as this was my first quesiton on the community.
Thanks a lot!

Hi @Anonymous ,

You can create a calculated column as below to get it, please find the details in the attachment.

Column = 
VAR _submit =
    CALCULATE (
        SUM ( 'Table'[Submitted] ),
        FILTER ( 'Table', 'Table'[Month_Year] <= EARLIER ( 'Table'[Month_Year] ) )
    )
VAR _clear =
    CALCULATE (
        SUM ( 'Table'[Total_Cleared] ),
        FILTER ( 'Table', 'Table'[Month_Year] <= EARLIER ( 'Table'[Month_Year] ) )
    )
RETURN
    _submit - _clear

If the above one can't help you, could you please provide more raw data in your table (exclude sensitive data) with Text format, your column chart field settings and your expected result with backend logic and special examples? It would be helpful to find out the solution.
