Drapp,
Changing the entry date on a part with this high a MNS won't affect anything. We changed a small group of numbers several years ago. They had some history that had enough history to phase-in. We isolated these parts into a single source and when we generated a stock order on these parts, we got a negative order.
I would suggest that you isolate your RSG parts into one or two sources, (one for active parts and one for NS parts), adjust the entry date to current and track it from there. One problem you will still have is that the MNS will still be 11 MNS.
If you want to email me directly at
chartle@partsedge.com or call me at (800) 825-7562, I will explain to you how you can adjust these so that you won't have to alter the entry date. I can't write about it here.
