Last three months count in Month wise table

[chanchalsharma]

Hi All ,

I have a requirement I have to show Month wise customer count in table where in one expression need to display count of customer code and in next expression need to display customer count of  last 3 month in respect of that month .

For example if first row for Jan 2015 ,last 3 month count of customer would be Nov ,Dec and Jan .

in next row Feb 2015 ,last three month would be Dec ,Jan and Feb .

I used rangesum function but it is giving me sum of last 3 row which is incorrect  .

    RangeSum(above(Count(distinct{<_Flag={'SD WOD_DOD'}>}CustomerCode),0,3))

then I pass condition for last 3 month in set analysis but it is giving same value as month wise value .

  Count(distinct{< _Flag={'SD WOD_DOD'},CommonDate ={">=$(=num(MonthStart(Date(Max(CommonDate)-90))))<=$(=num(MonthStart(Date(Max(CommonDate)))))"}>}CustomerCode)

Please check both expresion which I used ,help me out .

If any another solution can be provided, would very helpful .

Thanks in Advance

try this?

=Count(distinct{< CommonDate= ,_Flag={'SD WOD_DOD'},

CommonDate ={">=$(=Date(Max(CommonDate)-90,'DD/MMM/YYYY'))<=$(=Date(Max(CommonDate),'DD/MMM/YYYY'))"} >} CustomerCode)

Note: Format of Common Date should be 'DD/MMM/YYYY'

HI,

Second expression should work, but all you need to do is suppress the selections of other filters related to the year, month , quarter...

So your expression will be like below.

  Count(distinct{< _Flag={'SD WOD_DOD'},CommonDate ={">=$(=num(MonthStart(Date(Max(CommonDate)-90))))<=$(=num(MonthStart(Date(Max(CommonDate)))))"}, Year = ,Month = , Quarter=>}CustomerCode)

Use of Num() will work only if CommonDate is into numeric form, else it will not work

Sure .

823 is distinct count of customer code of Dec ,Nov and Oct month for December.

In Excel I did this mannualy .

Same number I need in qlik in Last 3 months .

Hi,

I have made some changes in script to make it work.

It cant be achieve using set analysis, because the Max or any other aggregate function in  set analysis is evaluated at overall level not at dimension level.

Hope this will solve your issue.
