Hi Nanda,
Thanks for look into this.
Yes, the variable which I created, I have to use that in another Formula variable in column section of the query designer with > condition.
For example my formula variable which I have to create "Forecast Amount" and the variable I created for 0calmonth is Z_calmnth which is a single value mandatory field.
So suppose user give the date like 102014 then "Forecast Amount" should show only those value which are > 102014 i.e. values for 112014, 122014 like that.
Regards,
Arindam
