while creating invoice or purchase order we need items to add.
<InvoiceLineAdd defMacro = "MACROTYPE">
<ItemRef> <!-- opt -->
<ListID>IDTYPE</ListID> <!-- opt -->
<FullName>STRTYPE</FullName> <!-- opt -->
</ItemRef>
Api fails, if item ref doesn't find the item on portal. So, while creating purchase order or invoice can we create item or add the item that is not on portal.
