We were very close with the last suggestion. Unisoft gave us a hand with the finishing touches:

For Entered vs. Printed, use

ADDITIONAL FIELDS, Transactions, Header Information, "Print Status". False = entered, True=Printed.

For partial receipt, look at ADDITIONAL FIELDS, Transactions, Header Information, "Number of Invoices". If > 0 then it is partial.

For completed, look at ADDITIONAL FIELDS, Transactions, Header Information, "Completed Status". True=completed.

Look only at the header of POs only (not receipts, returns or cost adjustments) by looking at "Document type" in the Header.
