Rolling time period using a dimension filter - Application error

Hi All,

I am trying to display rolling 13 months with reference to the month selected in the dimension filter. The code that I am using for the OnApply event of the dimension filter is:

APPLICATION.setVariableValue("ZE_CALMON", DS_ALL_MAIN.getFilterExt("0CALMONTH"));

However, whenever I am using the above or code similar to above I am getting the error "The Application does not exist.....". While processing the current request, an exception occurred which could not be handled by the application or the framework.....

This error is not appearing when I am removing the above code..it is occurring when I write Application.setVariable

I am not getting any code error .....I have tried the option of setting "load in script" to true but of no help.

Any idea why am I getting this error?

Thanks in advance
