How can we get GSR to pick up orders regardless of current on-hand availability?

Summary:

In order to use Oracle's suggested architecture to integrate OM, INV, OTM, and WMS, we need orders to interface into WMS regardless of current on hand balance. We do not see a way to accomplish this.

Client is a CPG company implementing Oracle OM, OTM, WMS, and INV. Oracle recommended architecture is that OM sends orders to INV and OTM, and INV then sends orders to WMS via the generate shipment request functionality (GSR). Shipments are planned in OTM and those are then interfaced to WMS. Note: if the planned shipment beats the orders into WMS, the integration fails with essentially an "Orders not found" error.
