When in the CCF admin console you may get an "Unable to update the requested information" when trying to add a new workflow or workflow step (from here I will just say workflow but I mean both). This is because you can not add a workflow when no others exist. i.e. DON'T delete the demo ones until you create one of your own.
What is happening is the ID field in the table in the database is used in a relationship and thus can not be an identify field. So the admin tool does a check for the highest value and adds one to it and uses it as the new ID. When there is no items it fails.
If you need to manually add a workflow in to the database (instead of doing a redeploy) it is in dbo.ContactCenterAIF.WorkflowsMaster and for workflow steps it is in dbo.ContactCenterAIF.WorkflowStepsMaster
