Well, you said a "33" is "your worst nightmare"... Are you referring to
the "33" (expedite scheduled receipt) or the "33" on the bottle of Rolling
Rock beer? I don't know which is worse.... :)
They brew Rolling Rock about 30 miles from our plant....

Terry,
You are correct.
The theory goes like this.
Let's say that an item has a LLC of 4. MRP will use this LLC to plan the
item in the proper order. So for example, if the LLC for all items is 0 -
7, then MRP will start planning on LLC 7. So LLC 4 will be planned after
7,6, and 5.
Now, let's suppose that a bill change causes the item's LLC to change from
LLC of 4 to an LLC of 7. This will result in the item being planned near
the beginning of the MRP run so as to ensure the higher level items (lower
LLC's) will see the demand correctly.
One more change, suppose we now delete the item from the LLC 7 level
leaving only the LLC 4 level. MAPICS does not change the LLC from 7 to 4.
So again, the MRP plan will plan the item near the beginning of the
planning run.
Normally, this does not cause an issue. However, let's suppose that over
the course of a few months (or years!) we don't reorganize the file. What
happens then? Well we would end up with many items at level 7 that should
not be. And depending upon the higher level relationships (i.e. does the
item appear in multiple bills at multiple LLC's?) MRP may not calculate
all of the demand accurately which can lead to some problems.
Most of the time this problem will have a symptom... the dreaded "33". For
those of you who do not know what the dreaded "33" is, let's just say that
as a planner it is your worse nightmare. (BTW what you don't know can hurt
you and your career!)
Hope that helps.

Correct me if I'm wrong, but doesn't MRP use the low level code to
determine the
item planning order so that it will not miss a demand. So if an item is at
the
wrong low level code, isn't possible the system could not plan an order for
an item.

Robert,
As usual you are correct. Everyone should take note of this as it has
caused much
confusion over the past few years.
The LLC is updated during BOM maitenance ONLY if the LLC is at a higher
level as
a result of the maintenance that is processed.
There was a problem with the Green Screen program having the incorrect LLC
which
was fixed on SH71748 (R6 PTF 6365, R7 PTF2919

I don't know what you mean about deleting components. If you are refering
to using
a component at level 4 in one bill and level 7 in another bill and then
later deleting
the level 7 component. If my memory serves me right, BoM maintenance never
reduced
the low level code only increased it.

Subject: Low level codes not in sync
The number one reason that low level codes get out of sync is
non-MAPICS
methods of changing data in the product strucure and / or
costing.
Check to make certain you do not have any non-MAPICS programs
updating
product structures. (i.e. someone with client access and MS
Access
Database)
You should run in dedicated mode because a reorg can effect
other
sub-systems besides product structures. ie. IM files, MO
files, MRP
files, MPSP files, etc.)
I monitor these files at least once a month. If they are out
of sync, I
try to determine the cause.
Also note: just deleting componenets from bills of material
can cause the
low level codes to be out of sync. If your running the latest
code, this
has been corrected in a PDF that the unattached job uses to
keep the files
in sync.
