OSP PO conversion from legacy system
When regular PO is converted from legacy system, we convert them with legacy PO number using FBDI.
For OSP PO, as the FBDI is not supported (OP Seq is not a column in Requisition FBDI) we need to either convert them manually or using API. As OSP PO can't be created without a requisition to be able to tie it to the work order (we can't use OSP enabled item), we need to first create the Requisition. How do we retain the legacy PO# when OSP Requisition is converted to PO?
