Is it not possible to match a prepayment invoice to a complex PO?

Summary:

It doesn't seem possible to locate Complex PO in the 'Matching Window'

Content (required):

For complex PO, I am unable to find the open PO lines (or receipts) to match a prepayment to.

Using same data and process, I am able to :

• Match standard invoice to complex PO (just by switching invoice type to Standard)
• Match standard and prepayment invoices to a non-complex PO

Is there some restriction on matching a prepayment to a complex PO or do I ned to rise an SR?
