Awesome tool and I would say, its need of the hour.

Now, I read this post on Microsoft Dynamics GP Support Blog on a tool that comes with Professional Services Tools Library (PSTL) to Prevent Users from Keying Incorrect Document Dates in GP 2010.

But unfortunately, scope of this tool is limited to following transaction entries:

1. Payables Transaction Entry
2. Receivables Transaction Entry
3. Invoice Entry
4. PM Manual Payment Entry
5. SOP Entry
6. IV Transaction Entry
7. Cash Receipts Entry

I would have expected this to have even more reach, especially on POP side. Today, just today, I received a bunch of PO Invoices being posted on a wrong date. I would have loved to have this tool on my environment had this covered much more types of transactions.

However, this is still very good than reinventing this by developers or partners.
