RE: Bogus Location Transactions

["Bailey, Dick" <Dick_Bailey@xxxxxxxx>]

        Al:

I'm glad you figured out your problem - because we haven't seen creation of
extra bogus transactions.

        As to your questions, the updating of IWI balances is done not by
INV900 but one of the other month-end program steps, and I'll get that
program number.

        We are still trying to get the BMR (s) to fix the ILI problem; there
are two that appear to address it (from the description) and we're trying to
get hold of them. They apply to 6.1, however, and it looks like you're on
4.05.

        Dick

                from Al Macintyre BPCS 405 CD Rel 2 OS/400 V4R3

                One of my collegues tracked down what is triggering this
problem that we have 
                discovered in the last 2 days, and there is now a
modification request to 
                change the JIT600 screen to prevent negative input to
rejects or good 
                quantity.  

                We previously did a modification to block fractional
quantities because some 
                people had been keying the hours data into the quantity
fields.  We also have 
                an occasional problem with people keying the shop order
number into the hours 
                field, so there has been some discussion about blocking
hours input that 
                exceeds 25 (valid for a machine running continuously on the
day that the 
                daylight savings changes).

                I had previously suggested that it was valid to deliberately
key negatives 
                there as a way of backing out discoveries of incorrectly
entered 
                transactions, but since the field minus key is very close to
the field exit 
                key on some keyboards, this can happen by el typo error.  We
now speculate 
                that quantity minus in JIT600 is a scenario that was
inconceivable to SSA 
                programmers so that their testing failed to explore that the
software working 
                correctly there, so that negative input there is not a safe
action.

                We found 10 other apparent field minus errors dating back to
February.

                Using our test environment Jerry duplicated the scenario, so
we are pretty 
                certain of the explanation.

                When different people are entering labor transactions, BPCS
assigns ticket 
                numbers that apply globally to everyone who is entering
them, in sequence.  
                When one person enters a negative quantity rejected,
apparently BPCS grabs 
                other transactions that have not yet been posted, from
current batches in 
                process, and declares them to be under lot control, and some
of the relevant 
                actions get processed & some do not.

                Which transactions get doubled or tripled is all the timing
problem of whose 
                data is in unposted batch status at the time that the
negative input gets 
                processed.
