vbajock,
There is a process called Consolidate Orders. This will take the line items of a group of Order Entry Orders for a common customer and create a new order. This new order would then be invoiced as a single order. The only problem with this is that the line items don't sum up. That is to say that if you have several orders with the same line item on them, on the consolidated order, you will have the same number of instances of this line item as there were orders for them.
Let me guess, you are trying to consolidate a number of EDI orders for a single bill to location?
