POWL : Changing Default Query

Hi

I am trying to change default Query to select using Last 7 Days instead of All.

But changes I make do not seem to work

Feeder    /SAPSRM/CL_CLL_POWLT_RFQ

Query ID SAPSRM_SP_SOURCING_01_01

Type       SAPSRM_FEEDER_RFQ

I changed Query Parameters Processed Since from Blank to 3.

Thank You

Nikhil
