The Access Control (SCRACS) page, although not considered a collaboration setup page, is where the action to invoke collaboration is given for a user as determined by the combination of security role and resource group to which the transaction belongs. The check box is labeled Collaborate just as the control found on the Transaction Control page that enables the collaboration feature for a given transaction code.
Please consult the "Access Control" topic in the CGI Advantage Security Administration User Guide, for more information on these security settings.
