Microsoft Dynamics GP requires each sales order to have an Order Type. For orders submitted through Microsoft CRM, Sales Users can either specify the Order Type explicitly with each Sales Order (the CRM Sales Order form is customized to contain the Great Plains Order Type), or the administrator can set a default Order Type through the Settings and Administration Tool. This Order Type will be used if an Order Type is not specified in the Sales Order submitted through Microsoft CRM. If an Order Type is not set either in the Settings and Administration Tool or specified in the Microsoft CRM Sales Order, the following error will be received when a Sales Order is submitted through Microsoft CRM (after the CRM Connector for GP is installed): 

“Procedure or Function 'taSopHdrIvcInsert' expects parameter '@I_vDOCID', which was not supplied.”

In order to be able to specify an Order Type in a Microsoft CRM Sales Order or set a default Order Type in the Settings and Administration Tool, you need to migrate any existing Order Types from GP to CRM through the Data Synchronization Tool after deploying the CRM Connector for GP (all Order Types created subsequent to the CRM Connector for GP installation will be automatically synchronized and do not need to be migrated using this tool).
