How can we pass macro filters value to URL?

[Vishnu Thogulu]

Hi techies
Usually prompt values are passed by &p_Paramatername=value or in the encoded form. It is working fine for general paramterized filters but not for filter with macros.
My filter is like this,
#prompt('Parametername','token','[TIMESTAMP_VALUE] = 2000-01-01T00:00:00')#

This filter is included for creating reports to find out the data for last month, last year etc (data grouping prompt). My value prompt has static choice.

Any idea?

Thanks
Vishnu
