Error during creating purchase orders using FBDI incase of award funding pattern

All of our projects are sponsored projects and therefore contract number is mandatory field while creating a Purchase Order. We have created award funding patterns so that users don't need to enter the contract details while creating the purchase orders. While this functionality is working in UI, we are not able to load the POs in bulk using FBDI without providing the contract number and funding source information.

The FBDI is running into error saying contract number and funding source information is required before creating this PO. Is there any way we can load the POs in bulk for projects with award funding pattern in place?
