RE: CMF - how could it be possible?

Assuming you have no modifications, and are not populating BPCS cost files
outside of std BPCS, then your most likely problem is low level codes.

Bucket  0 for item/fac/cost set is supposed to be a sum of all the other buckets
for that item/fac/cost set.   In bucket 0, "this level" should be a sum of all
the "this level" field in all CMF records with the same item#, facility & cost
set,  previous level should be a sum of the "previous level" in all the CMF
records for the same item#, facility & cost set.

Supposed to be, but sometimes isn't always.   Std BPCS cost manipulation
programs (CST100, CST500, CST600, etc) should manipulate costs so that bucket 0
is always an accurate total.  However, I have seen situations (in v4 and v6)
where this isn't true.  In all cases, the most common problem has been low level
codes on the item master.  These fields are also maintained by BPCS as bills of
material are maintained.  However, if the low level codes get messed up, you get
"unpredictable results" in MRP and cost rollups.   I know that there have been
some BMRS related to low level codes in v6.04 and v6.1.1.

The good news is that there is a re-set program for the low level codes, BOM900.
Be careful, though.  This program can take a long time to run and needs
dedicated file (see archives of this discussion group for comments about
increasing the efficiency of BOM900).

I suggest writing a query to ID all the bucket 0 records that are not a sum of
the detail records.  Then run BOM900, and re-run CST600.  Re-run your query and
see if the problem is fixed.   If it is, you need to get to the bottom of the
low level code problem, and possibly consider running BOM900 on a regular basis
until the problems are resolved.  If the problem is not fixed, we can start to
look elsewhere.

(NOTE:  it is also possible to write a query to ID records with potential low
level code problems.  )
