Problem with G/L period on some invoices

We have some invoices that are posting to G/L  (PSTPER/FLP08) with the wrong
period, meaning not what it should be based upon our inventory period end
calendar.  We use AFI.  We seem to have two recurring scenario's with
problems.  

First scenario is with some invoices created as part of normal product
shipment confirmation:
Period in A/R is correct (PPER15/SLP15)
Period in OE Invoice file is blank (PERN65/OEP65)
Period in AFI is blank (PRDN45/FIP45)

Second scenario is with manual invoices and credits (12 - 15 on OEP menu):
Period has same incorrect value in PERN65, PPER15 & PRDN45.

My suspicion is that the first scenario is related to some bug we've
introduced that is causing PERN65 to be blank and that the other files being
blank is a result of that. The second scenario might be situations where we
ran the end of month functions late, causing an "incorrect" default period
in the manual invoice/credit program.

Another general question is this, is the G/L period supposed to be based
upon current period in the inventory Calendar file, or where the invoice
date falls in the inventory period end control file.  It was my
understanding that you could post a single set of invoices that had dates
spanning two different G/L periods and that they would post to the correct
period, as opposed to simply going into the current period.  

I appreciate any feedback.
