Dave,
I didn't see your reply, so my reply is redundant. Dave is of course
correct.

Subject: Re: [MAPICS-L] Reorder point based on last order date
If you were using a controlled warehouse with shelf life control on the
item, the system would make any remaining quantity unavailable at the
expiration of the designated life. There's a lot of overhead to doing this,
though, in maintaining the locations, batch ID and date, etc.
Short of that, I think you could do a better job in MRP than order point.
Safety stock in MRP is placed in the plan one lead time in the future - to
avoid expediting just to have something on the shelf. What this does, in
effect, is "use up" the safety quantity one lead time ahead (in the future)
from the "current date". Every time you move the current date forward (most
companies do this once a week), the "use up" date moves, too, so this is not
exactly what you want. It will, however, recommend replenishment tied to
that future "usage" which is really an assumption that the stuff will no
longer be available beyond actual planned usage.
In addition, MRP gives you more flexibility in lot sizing (not tied to
simple order quantity as in order point) and gives visibility to future
requirements and future planned orders (not just waiting for it to appear on
the list when it's time to order based on usage - MRP looks ahead to planned
usage as well, order point does not).

subject: [MAPICS-L] Reorder point based on last order date
List-
We have some product that has a shelf life of 90 days. We order it 5
gallons at a time. Currently we have our reorder point set at 1 gallon and
are using IM-> Reorder Recomendations not MRP for reordering.
We want to make sure to reorder it before the product expires or when our
on-hand stock gets below 1 gallon.
Any thoughts or suggestions on how to do this would be helpful. If MRP is
helpful for this please suggest that too. Also, we are currently using an
uncontrolled warehouse for this item.
Thanks.
