I just discovered this morning that the canned RNI report in GP does not include items that have been received and not invoiced that are on closed POs. This to me is a glaring error in the canned report. Therefore, I would advise everyone to use the SmartList RNI as it does include data from closed POs. Of course, if you're a masochist, you could modify the canned RNI report in Report Writer.
Apparently when I reconciled the Purchase Accrual account to the canned RNI for a client earlier this year, none of their purchase orders were closed.
Therefore, the recommendation in my previous post to reconcile your SmartList RNI to your canned RNI is invalid.
