2 Months ago date filter

[Taboka]

Hi all,
I am using the filter below to get values for 2 months ago:
[Recharge Monthly].[Time Month].[Time Month Key]=(if( substring(to_char(?FromDate?),5,2) = 01)
then ((?FromDate? - 89)-1)
else if( substring(to_char(?FromDate?),5,2) = 02)
then (?FromDate? - 89)
else (?FromDate? - 2))

It works for the instance where the month selected is January,i.e I get results for the previous Dec.However when I test it on the instance where the month selected is Feb(where I'm supposed to get results for the previous Dec),it doesn't return any results.
Could someone maybe help me figure that one out.

Thanks\Regards

Hi everyone,
I realised the problem was my math in calculating the previous Dec from a selected month of Feb.The correct filter is therefore
[Recharge Monthly].[Time Month].[Time Month Key]=(if( substring(to_char(?FromDate?),5,2) = 01)
then ((?FromDate? - 89)-1)
else if( substring(to_char(?FromDate?),5,2) = 02)
then (?FromDate? - 90)
else (?FromDate? - 2))
and it works like a charm.

Hope this helps someone.

Cheers

you could have used add_months([date item] , -2 ) for that

Add_months and other add_* functions are great indeed.
