Synchronization Rule Selection in a Workflow

Hi,

I'm trying to get a grasp of using MPRs, Workflows, Sets to manage users from the FIM portal, instead my current method of using rules extensions.  When trying to define a workflow, using a sync rule action, the drop down to select the sync rule only shows the inbound sync rules.  Why not the outbound ones.  That's the one I need to select.

I didn't see any settings in the portal that looked to control this.  Is there a configuration value somewhere that needs to be changed?

Thanks,

Greg
