I need to load a standard PO via interface. In interface tables there are multiple lines using a single ITEM_ID, only changing ITEM_DESCRIPTION.
This ITEM_ID is a service, each line represents a detail of this service.
After executing import process, in PO_LINES there is a single line with total amount.
Unfortunately, there is no way to do this using PDOI... Try using the private api po_interface_s.create_document. But, the problem is you might not be able to use it as such... have to copy this API and modify it as required.
