Change Request Management Configurations

I have configured the Service Desk correctly. My service desk works fine without any problem. Now with if the Service Desk message is a Change Request then I could click on the Action to  "Create Change Document" to create a change request.

I would like know the following:

Do I need to configure the Change Request Management and TMS if I wan to use this functionality?

Well, even though I didn’t configure the ChaRM, I was able create the Change request management ticket. I am in change mode and I clicked on the Status icon to change to Status; everything is grayed out. I can not make any changes. Also, I am missing all the ACTIONS…when I click on the Actions I get this error " There are no actions in the worklist with Message no. SPPF_VIEW_CRM101"

I am using Solution Manager 4.0 SP 11.

Any help would be much much appreciated

Thanks
