Consolidating Configured and Non-Configured Items from one Dropship SO into one PO

We have a requirement where a single dropship Sales Order should generate only one Purchase Order, even when the Sales Order contains both configured and non-configured item lines.

Currently, we have enabled the "Consolidate Online Requisitions into Fewer Purchase Orders" opt-in and have disabled "Create Orders Immediately After Requisition Import" under Configure Requisition Business Function. We also have a CTO BPA for configured items and a standard BPA for non-configured items.

After submitting the Sales Order, separate requisitions are created for each Sales Order lines. However, after this running the Generate Orders process, the system creates two POs—one sourcing from the CTO BPA and one from the standard BPA.
