Purchase Orders imported in INCOMPLETE status

Hi,

We are importing Purchase Orders from R12.1.3 to R12.2.4 through Purchase Order Open Interface program (POXPOPDOI).

Our intention is to import the POs in an APPROVED status, hence in the Header Interface table we are setting the column APPROVAL_STATUS to APPROVED.

Though most POs are importing in an APPROVED status, due to from missing setups (e.g. missing Exchange Rates etc) some POs are importing in an INCOMPLETE status.

I would like to know

1)If there is an option to reject these POs rather than importing in an INCOMPLETE status

2)Is there an API/Concurrent Program to set the status of Imported POs to APPROVED, after fixing the missing setups.
