Can somebody pls help me?

I used the formula: rangeavg(above(COUNT([Incident ID]),0,3)) to calculate the three month running average but the calculation stops at the month of october.

I also tried : linest_m(total aggr(if(Count([Incident ID]),Count([Incident ID])),[INC Closed Time.autoCalendar.YearMonth]),[INC Closed Time.autoCalendar.YearMonth])*only({1}[INC Closed Time.autoCalendar.YearMonth])+linest_b(total aggr(if(Count([Incident ID]),Count([Incident ID])),[INC Closed Time.autoCalendar.YearMonth]),[INC Closed Time.autoCalendar.YearMonth]) to calculate the predicted value for Nov/Dec/January but was an obviate attempt.

Looking forward to hear from the community.

Would you be able to share the qvf where you are trying this? Will be easy to troubleshoot from there

Hi Niteen -

I see you are only loading data until 2017-sep. If you won't have oct, nov, and dec in you app, they won't get calculated. Now this may be how it is only in the sample app, whereas your original app might have it. But this would be a good starting point to check. Do you even have those three months in your application or not?

Hi Sunny, I don't have the next three months (oct/nov/dec) in my app and that is precisely my question. How can I show next three month and the corresponding predicted count of tickets based on the last three month ticket data?  These data files are monthly files with count of tickets

Cheers, Niteen.

Just concatenate those three into your main field

Table:

LOAD

    "Incident ID",

    "INC Closed Time"

FROM [lib://Downloads/Ticket Forecasting Problem.xlsx]

(ooxml, embedded labels, table is Sheet1);

Concatenate (Table)

LOAD Date(Date#("INC Closed Time", 'DD/MM/YYYY')) as "INC Closed Time"

INLINE [

INC Closed Time

01/10/2017

01/11/2017

01/12/2017

];

Thanks Sunny. With your help i managed to get the months as a dimension. How about calculating the foretasted value for these months? How should the formula look like. Thanks again.

Cheers, Niteen

I think your initial formula should work... if it isn't would you be able to share the app with those dates in the app?
