What options are available for working with synchronised data in Standard ERP, other than POS? There are lots of options in various places but little documentation about what they do. For example:

In TC > Settings are a few settings relating to Sync.
In User Settings > Settings > Local Machine are options Enable Offline Email and Enable Offline Orders.

I'm particularly interested in knowing if Standard ERP has a feature for offline contacts, or anything else CRM-related.
