RE: CIC.ICACT / CIC.ICLEVL -- BPCS-L

Hi Al

On our V6.1, every CIC.ICLEVL for all records are equal to zero. The BOM low
level code resides in the item master, IIM.ILEVL. It is indeed the lowest
level an item can exist in a BOM structure. This is capital information for
MRP planning. MRP calculation starts with all top level items, or level 0,
then level 1, level 2 , ...etc. This is by logic: an item can only be
planned only after all of it's above requirements are calculated before.


In 4 years now, I never had to run the reorg program BOM900D to recalculate
IIM.ILEVL. We have 15000 active items and 150 000 BOM lines across 5
facilities. Looks you definitely needed a clean-up of IIM.ILEVL.

We are 405 CD mixed mode, multi-facility, heavily modified.

Several weeks ago I asked

>Under what circumstances would this field still be "Y" after all 
>facilities have had MRP500 MRP600?

I got back a bunch of suggestions of things to look into, for which I am 
much appreciative.
Did I neglect to say THANK YOU?

Those suggestions were a big help.  There are now approx 1,000 items being 
planned properly, that were not, when I stumbled over this.  There's a 
bunch of items that MRP is ignoring because of coding errors that I passed 
on to the folks at the office who manage such things ... parts we 
manufacture but have no BOM, parts that we both manufacture and purchase.

Some coding errors I fixed with one of my fixit programs ... if this or 
that field is blank, populate it with our default.  This is on a menu where 
we can rerun the fixit periodically, to get new items whose input might 
have neglected some stuff.

For those fixed 1,000 items, CIC.ICACT still "Y" after MPS MPS MRP meant 
that these items needed to be planned, but our data was too screwed up to 
permit them to be planned.

I cleared out all the "Y" to see if any were ancient in perpetuity.
I now run complex facilities using MPS MPS MRP instead of just MPS MRP.

Some of the items there had negative requirements, then after BPCS file 
reorg, they got planned properly.

But, excluding items awaiting engineering repairs, there are still about 
400 items, that after I run MPS MPS MRP, the CIC.ICACT field is still "Y"

I looked into a few of them in detail ... what SHOULD MRP have done with 
this item?
Aha ... for some of them the answer was NOTHING

For example ... we have one that is a sub-assembly ... the higher parent 
needed 250 quantity ... this item made 250, the higher parent used the 250 
... the shop order on the higher parent is still open (there are later 
steps not yet completed that do not use this child)
so I wondering if, in some cases CIC.ICACT still "Y" after MPS MPS MRP 
means that the item is still MRP-active but no MRP planning is called for.

It would be nice if I knew how to detect situations calling for different 
responses by us
    * These items need MRP planning but their coding is screwed up ... 
human repairs needed
    * These items are MRP active but do not need MRP planning ... humans 
may ignore (not a problem)
    * These items need MRP planning ... perhaps we missed a step when doing
it
    * Something else going on here

In searching for clues, I was using queries that gave info on various 
fields of these items in CIC IIM ILI and other files ... I would run this 
one facility at a time.  For a while it was useful to include the IIM BOM 
sequence field ... which of these items have BOM components in ANY 
facility, but I would also like to see which of these might have BOM 
glitches in the same facility ... before I do query linkage with MBM file, 
I wondered if there was an equivalent to IM.INSEQ (last BOM Sequence for 
all facilities) at the facility level.

What is the significance of CIC.ICLEVL field?
Is that how many levels deep an item is in BOM in that facility?
