We started using POs in mid 2006.  We only used them to create POs and receive to inventory.  All invoices were handled as vouchers.
I have no G/L entries during that time.
 
Mid 2007 we started using PO-N to create AP entries.  Starting about that time I have many RNI/Invoiced entries without the matching RECEIVED/NOT INVOICED entries.  I'm think, and looking for confirmation, that some invoices were reconciled to PO receivers that didn't have G/L entries.
 
I think I have most of it reconciled now but I am trying to document what I did.  It seems that I had to set a flag somewhere for PO to or not to make RECEIVED/NOT INVOICED entries but I can't remember where.
 
Does this sound correct and can someone help me remember where I found that setting.
