Hi La-Qa,
The only pre-requisite before importing the CA Service Management content is to create the servicemanagement organization as you can see in the screenshot in the link provided.
I have been trying to reproduce the issue internally but no luck so far. I think the best option here is to check the steps you are following and the environment through a webex session. Please open a new case and provide: the details of the issue, step by step to reproduce the issue and the jasperserver.log.
Regards,
Pablo
