Re: Changing Bills of Material

[jclayton@xxxxxxxxxxxxxxx]

I have used the following approach successfully in the past :

- Change item ABCD's Item type to a Phantom

- Structure Item ZYXW as a component of ABCD

- MRP,IM,etc wil consume the old item until there is insufficient stock,
and then switch to using the new one

- One thing  to watch - if BOH of ABCD gets down to say 1lb, and an order
comes along for 5lb - it will use the new item - but the 1lb could be used
later if an order came along which needed 1lb or less. You may still have
to manually controll the disposition of the final bit of stock.

- Once the stock of ABCD has been exhausted, you can then do a PSF mass
replace of ABCD with ZYXW, etc.

Subject:  Changing Bills of Material


I'm looking to do a quantity based cutoff for a raw material.  I've used
the
effective dates in the Product Structure for time based cutoffs, is there
something similar for quantity?

We have a item 12345 that uses 1 lb of ABCD.  We have 500 lb that we own.
We want to switch from ABCD to ZYXW.  We want MRP to prompt us to buy ZYXW
instead of ABCD.

We are running REP and I know that in a released REP schedule I can put in
a
cutoff quantity but I need to effect the change further out than we release
our schedules.

Any ideas would be appreciated.

Thanks
