Rob,

I clearly see what you are saying. If the example were written in RPG2
or 3, I might be able to grasp it (It is hard to change an old person
like me).

Actually, when I first did the ADDPFTRG, I was HOPING that I could
simply key a SELECT statement which would only FIRE the trigger when a
certain Vendor # was "accessed".

Thanks,
Don

But you're forgetting the whole point of a trigger!

Ok, now for a little history...

Back in the dark ages one would have the Never Ending Program (NEP) that
would occasional query the database for changes. If it found any, it
would perform the actions you are talking about. I have a coworker who
installed one of these in the last year or two despite my STRONG
encouragement to use a trigger.

Then they came up with triggers. Why do you insist on querying the
database for changes? The G..D... trigger has the changes in it. You
do not need to restore a before and after image someplace to see what
was changed. They are passed as parameters to the trigger. Please see
the two data structures NEW and OLD in the sample I posted.

In your technique if someone updates three PO's you are going to query
the whole stinking database 3 times looking for any changes. However,
if you use a trigger you would already know which particular PO got
updated during the trigger by looking at the fields in the datastructure
NEW. If you wanted to know if the PO status field changed you could
compare NEW.PSTAT against OLD.PSTAT (we're running BPCSCD also).

Thank You. My hope is renewed. I had that thought in the back of my
mind!

You can. See http://code.midrange.com/index.php?id=2b2560d170

The trick is to accept the parameters (buffer) and pass it to the
programs that perform the processing. In your case, if you just want to
email, accept the parameters and don't update anything.

Never having learned much more coding than RPG 2, I guess I was hoping
for a simple way to trigger just a CLP - which would probably contain a
query or two which would "select" out only the records for the vendor in
question, and only those which have been changed or added since last
"trigger". Then, probably an auto PC support download, and an email
with attachment out to the vendor. I had these visions

Yes it should "be work". But it won't work. :-)

When a trigger is fired many parameters are implicitly added. Including
such information as to what file, in what library, was updated. Also
what the record format look like before, and after, the change. That
way you can automatically do stuff like "I only care if they changed
certain fields on the PO. Like, if they changed the shipping address I
could not care. But if they changed the status to say shipped I want to
send a notice to the customer that it was shipped at this date/time on
this truck.

Now, with all the parameters automatically sent to the program you
should NOT chain back to the file that the trigger was based on. Why
would you have a need to? All the information is in the parameters.
Unless you are doing something really weird like sending the customer a
list of, not only this po, but all po's they have with you.

(As I am typing I just realized that I am confusing PO's, customers and
vendors - try to get past that.)

Thanks, Rob. I will now have to STUDY a lot more!

I still think my "simple" idea should be work. :-)

This said to look at previous messages, but there were none??

Message . . . . : Error occurred in trigger program.



Cause . . . . . : The trigger program which was called as the result
of a
database insert, update, delete, or read operation failed. See the
previous
messages in the job log to determine the error. The error code is 2
for
trigger POTRIGGER in library BPCSCDUSR type *SYS. This error code can
be
used to determine the trigger which caused the error, as follows:

1 -- *BEFORE *INSERT trigger

2 -- *AFTER *INSERT trigger

3 -- *BEFORE *UPDATE trigger

4 -- *AFTER *UPDATE trigger

5 -- *BEFORE *DELETE trigger

6 -- *AFTER *DELETE trigger

We do have BPCS. Sounds very simple. Unless you are really banging out
purchase orders you shouldn't have to have a NEP job processing trigger
requests. Heck the key think time may be more significant. After all,
how many people would submit that process off as a batch job to PO Entry
versus online if they were doing it by modifying the PO programs versus
a trigger? A few? At least, sure.

If you need a sample shell to work with let me know.

Sounds like a plan. I would separate the task into two tasks: the
trigger that accepts the changes, and a submitted or never-ending job
that creates PDFs, sends email, etc. The trigger process should be as
lightweight as possible since it's fired for each row processed. This
also allows you to change the feature set in the future without
necessarily changing the trigger program.

We don't have BPCS so can't comment on the actual files used.

HTH,
Loyd

One of our mfg. outsourcing suppliers would like to know whenever we
create/modify a P.O. (BPCS HPH/HPO) against their vendor number.

Although I've never done this, I was wondering if a trigger could be
assigned to these files, then at least an email, or email with say a pdf
or excel file attachment, would be automatically sent to their company.

Thanks in advance!
