Set KB Date for Catalog CTO page

HI Friends,

I want to change the KB Date while clicking configure link for a CTO product in catalog.

I found a badi crm_config_badi- set_kb_date, but this badi triggers for crmd_order and cto from basket.

This doenst trigger when browsing catalog.

could you tell me how to pass the new KB_date for the CTO in catalog?

The reason for me to change the Kb date is based on that date it will pick the version which is valid on this date and my char values gets changed dependending on the version, so i want to hcange it.

Please give me some inputs on this,

thanks alot
