Demand Management

Hello, our company is in the process of implementing EDI and I was looking for some documentation, how to guides, work instructions, anything that could help us better understand the Demand Management Module/Process.  We have the tech guide that Epicor provides, and I am using it to the best of my knowledge.  I am using a test system, I have an 830 file converted and ready to import, I am just trying to step through the whole process from importing a file to creating a sales order.  Any knowledge, documentation, and/or assistance would be greatly appreciated.  We are using Epicor 9.05.702A and eVision.
