Ex Part # 123 is 12 MNS and you order one. When order is received MNS resets to zero to match MNR.
Pros and cons? Other than the idea that someone could DS zero an aged on hand and post in back in to make old inventory look newer.
MNS and MNR are
both needed to accurately age all parts in your inventory. They are both great pieces of information. Not understood or used incorrectly can cause a lot of inventory issues. Clearing the MNS field with each receipt was never a true "need" but since so many misunderstand how to age a part accurately, they added this feature. Turn it on, turn it off - I'm good with either decision - as long as you understand what's happening behind the scenes.
Let's say you have a part on your shelf that hasn't sold in 8 months. Someone buys that part. Five minutes later they return that part. YOUR MNS HAS BEEN RESET - AND THE RETURN WILL NOT PUT THE MNS FIELD BACK TO WHAT IT WAS. However, the MNR still shows the last time you bought it (or at least the last piece/part)
Let's say you have two alternators on your shelf. They are both 13 months old. Someone buys one of them. The MNS is now reset. How old is the other alternator still on the shelf? 13 months. What does the computer say MNS is... "blank". This is why MNR needs to be considered. I see PM's all the time forget this and build idle reports or use MSR the wrong way - causes idle buildup and they miss return opportunities. Lets say that other part was on the locater at 50% off and you only have MNS setup on the locator to discount parts.... that other one just fell off the discounted list!
MNS shouldn't be used ALONE.... MNS and MNR work together.
