RE: AMI3G -- MAPICS-L

Thanks, Ann. I was wondering what happened if MDCC sent a transaction to
TRDATA at the same time I would be inloading the hand-entered transactions.

Joan,

When you do the
  *Lock         In        ZNXTRN                               91
statement, test if *IN91 is on because if another program has a lock on
ZNXTRN already, OS/400 tries for 30 seconds to get a lock and then just
falls on through to the next statement.  Our code is:
TRNTAG            TAG
*LOCK                in(E)             ZNXTRN
                          IF                %ERROR = *ON
                          GOTO          TRNTAG
(this is the ONLY time I ever use a GOTO)  Just loops until it gets a lock.
We were getting duplicate transaction numbers for years and finally figured
out that if ZNXTRN was already locked, the code was falling through and
giving the next number (same number) to multiple transactions.  One actually
had a lock, the other(s) not.  Our save-while-active had it locked while
data collection scans/green-screen entries were continuing to process -
sending transactions and getting the duplicates.

Happy coding,
Ann

"A followup question - and I need the answer yesterday! (nach) Steve, what
do you do about creating the transaction numbers? If you leave the field
blank, does TRDATA processing generate the "next" number needed, or do you
have a number series that you use to populate the transaction number as you
populate the TRDATA records?"

Yes; on your program, you need to read a data area called ZNXTRN and maybe
do something like (somebody from the list helped me once):
C     Pull_Trans#   Begsr
C                   Clear                   znxtrn
C                   Clear                   *In91
C     *Dtaara       Define                  ZNXTRN
C                   Dou       *In91 = *Off
<-----|
C     *Lock         In        ZNXTRN                               91
|
C                   Enddo
<-----|
C                   Dou       *In91 = *Off
<-----|
C                   Eval      ZNXTRN = ZNXTRN + 1
|
|
C                   If        ZNXTRN = 0
|
C                   Eval      ZNXTRN = 1
|
C                   Endif
|
|
C     ZNXTRN        setll     TRDataz0                               91
|
C                   Enddo
<-----|
C                   Out       ZNXTRN
C                   Endsr

You will get the idea.  HTH!
