Hide the SOURCE OF SUPPLY table in SC screen

Hi all,

I am working on SRm 7.1 and new to WEBDYNPRO.

My requirement is to hide the SOURCE OF SUPPLY table under SOURCE OF SUPPLY/SERVICE AGENTS tab.

When I'm trying to impleent that through an enahcenmenet of the web dynrpo iview,I see the following error after I try removing the UI elemnt SOS_CONTAINER.

*ACC: Label for MeltingGroup-like Container "TOP_CONTAINER" is not set     *

Is this the correct way I'm doing or is there any other way I can hide the SOURCE OF SUPPLY table in Shopping cart screen?

Please advise.
