The problem with user defined fields is multifold. One, many of the
tables I am considering do not use them. Two, many of the columns I want
to add have timestamps and whatnot and I want the system to maintain them
and I do not want to rely upon RPG tricks to overlay a timestamp into some
character column, nor do I wish to always have to translate said
conversion every time I want to query by that column. Triggers and User
Defined Functions (and maybe even a view utilizing some of those UDF's)
would take out a lot of that pain.
But what it really boils down to is that I want to add some very specific
columns without disrupting the business by having Infor programs blow up.

Depending on the version of BPCS/LX you are implementing in ERPLX 8.3.4
Infor has added some user defined fields for a lot of the master files to
help rectify the use of extension files and doing data base changes to the
base physical files.

John,
What should I be comparing, and why? Is this an attempt to find out what
changed? I'm not trying to find out past tense. I am trying to decide on
the possible negative ramifications of adding additional columns to
existing tables.
At first I thought I dodged the bullet since Infor seemed to have used the
logicals for all traditional RPG I/O. Their logicals select the
individual columns from the base tables and avoid any *ALL concept. This
is a good thing. No programs would blow due to a record format level
check.
But then it was pointed out to me that Infor does occasionally use the
dreaded:
select * from mytable into :mytableDS in which mytableDS is an
externally defined data structure. At one time this would have only been
a 'soft' error. But many moons ago IBM came out with a ptf or new release
which made this a hard halt if the 'from' table was altered and now had
more columns at the end than were in the data structure. Oh, it's a
really simple fix. Simply recompile the program and it will use the new
external data structure. I'm not saying the mountain is insurmountable,
you just have to know whether the changes you want are worth the pain.
As far as any concerns about Infor screwing up the additional columns I'm
somewhat confident they wouldn't. For example if they do a traditional
RPG input, modify some columns and update the row the columns I an
interested in are outside of their control and shouldn't be altered by
that. But I would definitely test that out.
I have zero interest in a "needle in a haystack" solution.

fyi - from the help text
54=Compare file member
Type 54 to compare file members. You can only use this option
on data physical files (*FILE PF-DTA) or source physical files
(*FILE PF-SRC). If you try to use Compare file member on any
other type of object, you receive an error message.
