Loading Vouchers using Vendor ID SINGLE to Single Payment vouchers.

I am using PS AP 9.1 PT 8.53 and loading a file with voucher requests to use Vendor ID SINGLE and a default for Single Payment voucher style to VCHR_HDR_STG, VCHR_LINE_STG, VCHR_DIST_STG and VCHR_VNDR_STG. I activated the Custom Interfaces value in the translate and voucher tables, created an AP Origin SNGL with default banking inforrmation. Load the file to the stagin tables but when I run the Voucher Build but instead of loading to base voucher tables, the voucher build uses the quick invoice tables that accept only regular and prepaid vouchers. PeopleBooks states we can load voucehr data using EDI and XML to the staging
