SRM 7.0 Modify POWL for shopping cart check status screen

HI Experts,

The standard settings in check status for SC in SRM 7.0 is to display the sc with item level. This causes the SC number to be repeated (for no. of items in SC) and all links open the same SC in a new window.

We want to display only the header of SC and no item data should be displayed in check status.

I tried

SRM Server->Cross-Application Basic Settings->POWL and Advance Search->Adjust POWL Layout,search criteria and push buttons----choose feeder type SAPSRM_FEEDER_SC -double click field catalog-choose ITEM_DESCR, ITEM_NO, ITEM_STATUS---CHOOSE display and select HIDDEN COLUMN radio button.

This hides the corresponding columns but duplicate records are still showing.

Can some one please help?

Thanks,

Anubhav
