Re: MRP-MPS query

Sounds pretty good to me, except I would change the last sentence (which 
may have been a typo) to "This continues till end of explosion of all 
non-MPS items.".

For this to work correctly, you need to be sure that your non-MPS items do 
not have any children that are MPS items.  If a non-MPS item has a child 
that is an MPS item, MRP600 will generate requirements for the MPS Item, 
but since MRP500 (that plans the MPS items) has already been run, there 
will not be any planned orders generated for that MPS item.  I have seen 
this happen occasionally.  The Item low level codes (which should be 
maintained automatically during BOM maintenance) must also be correct.  If 
not, you could generate requirements for items that have already been planned.
