you need to use the CMDB Console "Service Catalog" to correctly define the Service Catalog (and offerings etc) for them to show up correctly.
Refer to the CMDB guides on how to do this.
Thanks for suggesting that, I have checked the service catalog console in CMDB but it is blank. I have already defined 7 Business Services using the Business Service form recently and I am able to see these business from Incident Console. Does anybody know why the service catalog is empty despite defining the services?
