Payables SLA R12.2.4

Hi All,

I need to write one ADR with 2 conditions, one for PO matched invoice and another for non PO invoices.

incase of non PO invoice, cost center should come from invoice distribution account and for PO invoice it should come from PO distribution account.

Please let me know which field on invoice I can use to write the condition. (some flag which is NULL for non PO and yes for PO)

Thank you
