As per further research,CON-SUSA-A15IPS9 is mapped to SKU ASA5515-IPS-K9, however it is not available in CCW. You can order SKU ASA5515-IPS-K9 without the service, and then order the service to your distributor (if you are a distributor, you may order it directly to Cisco).
As per system functionality, even if the service is mapped to a top part number but service is not available in CCW, system will not accept it, and you will just have an error in you configuration that might delay your order.
If you have any further questions/clarifications regarding this, we suggest that you open a case with the CCW Support Team for further investigation. Either create a case online at http://www.cisco.com/cisco/psn/web/workspace or by calling 1-800-553-6387 options 2 and 3.
If this is your first time to open a case using Customer Service Central, you will need to sign in to your My Cisco Workspace (http://www.cisco.com/cisco/psn/web/workspace) and then add the Customer Service Central module to your Workspace to open and manage your cases online. Help and support documentation is available on Operations Exchange.
