Issue in creating Amount based invoice

Summary:

Hi Team,

We are trying to create an amount based invoice against an amount based PO. In PO we are entering 'Supplier Item Num' in lines with value as 'Parts'

when data is inserted in AP_INVOICE_LINES_INTERFACE, the Supplier Item Num is mapped with vendor_item_num in AP_INVOICE_LINES_INTERFACE.

But the import Program is throwing error. Once we remove the value in vendor_item_num the invocie is getting created.

Our requirement is to create an Invoice which will also has 'Supplier Item Num' details.
