Re: Data base triggers

[Jim Langston <jlangston@xxxxxxxxxxxxxxxx>]

I believe you want to specify ALWREPCHG(*NO) on the ADDPFTRG
command.  Help for this is:

Allow Repeated Change (ALWREPCHG) - HELP

Specifies whether repeated changes to a record within a
trigger are allowed.

The possible values are:

*NO
  Repeated changes to a record within a trigger are not
  allowed

*YES
  Repeated changes to a record within a trigger are
  allowed.

>From what I understand, that means if a trigger program changes a record
if you have a *CHANGE trigger, it will be called if ALWREPCHG is set
to *YES, otherwise, it will not call it a second time.
