RE: Cost Roll Up -- BPCS-L

--
[ Picked text/plain from multipart/alternative ]
There are some people who can get confused as to how BPCS Costs supposed to
work.
Do you understand that Cost Bucket Zero is supposed to be the total of all
other cost buckets, not just One?

We have items that can be purchased or can be made.
Depending on volume, it can be more economical to go one way or the other.
I think in a situation like this we are better off using two different part
#s, one for purchased, one for made, but what ends up happening is the
parts get moved between different realities.
Now it is important to remove the cost data that belongs to the old
reality, but sometimes people neglect to do that, and now you have cost
ingredients for both purchased and made in the same part which guarantees
it won't calculate correctly.

I have a query/400 that lists contents of costs that are not in concert
with the kind of item it is.

Make sure you not have two or more people doing cost rollup at same
time.  The two runs can corrupt each other if hitting same combination
items facilities cost sets etc.
What can happen is you got too many cooks too busy to talk to each other.
One person changes some FRT MBM data and does a roll up of the items
involved, or all items if the change is to some common sub-assembly.
One person changes some LWK overhead rates, and does a roll up of a lot of
stuff to apply the new rules.
We can easily postulate other examples of how people doing perfectly
legitimate work, if they not communicate with each other, run this off of
two different JOBQ, or God Forbid do something on-line, could end up in
mutual conflict.

Sometimes people meant to key in some CST100 adjustment to a particular
item facility cost set etc. and did a keying error, oops caught themselves,
and keyed it to the correct place, not realizing that their error is
sitting in the wrong place for all time.  We call this HIDDEN COSTS when it
comes time to delete an item, we then find that some data has been sitting
some place it should have never been, perhaps corrupting our information
leading to decision why we are now deleting this item

I have pair of Query/400 - one CIC one CMF to display what data is out
there by some item because apparently when someone mind set is such that
some item belongs in some facility, they don't see the cost data that
exists in some other facility, and not realize that the blank stuff also
needs killing.

If you are operating by facility, you should not have any contents that are
blank in facility.
Create a Query/400 over CMF and CIC to get a count of records by facility
The fact that those invalid facility records somehow got in there by error
can lead to additional errors

We also on 405 CD and found random problems in CST900
1. Find IBM Manual on RPG - dig into the rounding rules when doing math in
the largest possible field sizes.
2. Find RPG Source code for CST900 CST500 etc. working with the fields that
end up with bad values.
3. Correlate whether the code is violating the IBM Manual on what is needed
for the rounding to work right.
4. I found the problem to be systemic in 405 CD ... now SSA may have fixed
what I found in some later version rewrite

Steve, Dee-Dee, and future responders
PLEASE
try to refrain from including all of some prior discussion that does not
seem relevant to latest
I have had my hands slapped more than once on topic of what some foreign
subscribers pay for in bandwidth
I recognize it is easier to reply to an unrelated topic when launching a
new one
I recognize that some people might read the question on top and not realize
the volume down under
