There is a new guide available to help partners navigate through the recently launched Order Central tool. You can access the Order Central Partner Quick Reference Guide for Microsoft Dynamics ERP - How to Process an Order on Order Central via PartnerSource.
Also, don't forgot about the highly rated, Chat Now service to contact Microsoft Dynamics Operations for questions regarding product orders, ordering policy, licensing, and registration keys. The Chat serviced enables you to contact the appropriate Regional Operations Center, which supports your business -- the European Operations Centre (supporting EMEA), Asia Pacific Operations Center (supporting APAC), or the Americas Operations Center (supporting North and South America). The instant chat option is available for immediate response from the Customer Care Team during normal Local Regional Operations Center business hours.
