I'm trying to produce a list of items that have been receipted 11 months ago or earlier.
I'm using rows to get an item no. list and I am using the formula below to get the last posting date of the last purchase receipt so that I can pivot the report and filter out the more recently receipted items.
=NL("Last","Item Ledger Entry","Posting Date","+Posting Date",NP("DateFilter",Options!C8,Today),"Item No.",C5,"Document Type","Purchase Receipt")
The date filter key is
Options!C8 is our go live date 01/11/11
Today is =NP("Eval","=today()")
The problem I'm having is that the list is generally OK but some items are showing no posting date even though there are plenty of purchase receipts in the item ledger.
Any thoughts?
