RE: Can I use a trigger to...

Yes. If you look at the database documentation for triggers, you will see
that an Escape message to the caller (not to the database, as I recall) will
result in the record not being added. Any and all programs that *might* add
rows to that table would then need to be able to handle that error.

Last night, being month end, we started our month end process at 6:00
pm.

Unfortunately, one person, in another time zone entered some
transactions
that were dated for 9/30 but were not included in the month end process
because her work was done after month end had finished.

Now the first offered solutions was to disable the subsystem, lock
users
out, allocate objects etc... which due to limited manpower and some
political logistics is impractical.

So I wondered if there is a way to use a before event trigger (before
add/update/delete) to detect if record maintenance was requested during
a
specific time period. I know that the trigger can detect the activity
but
is there a way to prevent the actual add, update or delete operation
from
occurring?

In looking at the ADDPFTRG command I didn't see any parms that might
address this.

I use the trigger template program from an article Jon and Susan did
awhile back (eserver iSeries edition January 2002).

In that code, could I simply overlay the new buffer with the old buffer
contents - effectively preventing an update?

But just as important, how would I prevent an add or delete?

Is this possible or are there other solutions?

Thanks!
