Hi there,

Do you want this to be changed on all task extended tables? Or just Change Request?

If Task extended, just change:

+ at the attributes: change knowledge_sarch=true into false.

If only Change Request, you could add an onLoad Client Script like:

function onLoad() {

	//Type appropriate comment here, and begin script below
	gel('lookup.change_request.field_name').outerHTML='';

}

Kind regards,
Mark
