Your company has a private cloud that contains a System Center 2012 Service Manager instance. Service Manager has the Self-Service Portal installed.

You create a service offering that contains a single request offering. The service offering provides logged-on users with the ability to add their user account automatically to a group named ServiceGroup1.

The company’s security policy requires that an administrator named Admin1 must approve all requests for group membership changes.

You need to configure the infrastructure to meet the requirements of the company’s security policy.

What should you modify?

A.
the service offering

B.
the service request template

C.
the request offering

D.
ther Service Offering Category list

I am brand new to SCSM/SCOrch and am fumbling my way through it. I have finally gotten a runbook successfully created, service request offering completed, and published it to the portal. I filled it out and submitted it on the portal a couple hours ago and it still sits “In progress”. I cannot for the life of me figure out how in the world to approve the request. I assume once I approve it the rest will be completed automatically.
Can anyone help? Please?

For approval you need to add a Review Activity to the Service Request Template at the Activity tab.
