Date an Invoice is Accounted (Posted to the GL)

Content

I need to build a BI Publisher report for accounted invoices that includes the date an invoice was accounted.  I'm aware that I can use AP_INVOICES_PKG.GET_POSTING_STATUS(INVOICE_ID) = 'Y' to determine if an invoice is accounted.  Is there a similar package/API to get the date an invoice is accounted?  If not, what table stores this date?
