[BPCS-L] INV970 INV973 SYS120 RGZPFM in EOM

[Alister Wm Macintyre <macwheel99@xxxxxxxxxxx>]

I just finished another month's end fiscal.

Because we will be doing physical inventory at end of December, I tried to 
clear out those locations whose inventory and requirements had gone to 
zero, because each valid ILI record can become a printed physical inventory 
tag, which I figure we only need on item-warehouse-location combinations 
active in December.

It has been a while since I included this "zero purge" in end-fiscal, 
because it takes a while to run.
I recognize that certain steps are only safe to run at certain points in an 
end fiscal cycle.

100% of the update jobs were run from the main console with the system in 
restricted state except for subsystems QBATCH and QSPL going ... I do it 
this way to prevent any co-worker from signing on while I am in the midst 
of critical stuff.
You see, except for people intimately involved in end-fiscal stuff, most 
users are freed from needing to comprehend the implications of disobeying 
"stay off until I tell you that you can get back on."  So by doing it this 
way, they are incapable of such disobedience, so I not have to worry about it.
This sandwiched between backup/400 GO SAVE 21 to different backup tapes 
before and after the whole shebang.

Right after INV900 I ran INV970, pausing only to check record counts via DSPFD
IWI = 37,436 with none deleted
ILI = 62,618 with none deleted
that's in IBM file terms
before & after, none changed but audit trail says it found 10,218 ILI 
records to be zero and claimed to delete them ... Oh they have record id LZ 
not LI so they are coded for BPCS deletion but not actually gone
so I ran SYS120 expecting that to remove them, but it did not
and I was signed off while SYS120 was running (I was signed on with a 
user-id that is not part of live environment to check to see when it got 
done) since I have learned that the reorg skips any files in use when it 
gets to them
Nothing else running concurrent with any of these steps

then I looked at INV973 code ... incidentally the program title is 
misleading ... then ran it
that took us to
IWI = 27,131 records with 10,305 deleted in IBM terms

But we still have 62,618 ILI records with a sizeable volume coded LID = 'LZ'

I was getting fatigued ... I had been at this for many hours, partly 
because we run a lot of end fiscal reports, and partly because I am looking 
at results at various steps to see if stuff seems Ok ... so I continued on 
to other steps

Later I plan to do SYS120 again to see if it removes any ILI whose related 
IWI now gone.

Then if the ILI record count has not gone down, after another backup I plan 
a later nite or weekend to do an IBM reorg where I tell RGZPFM to get rid 
of all ILI where LID is LZ.  I almost never touch RGZPFM since I consider 
it extremely dangerous ... what if I make a keying error?

I suspect some of these LZ have been there from past deletion efforts.

Is this how it is supposed to work?
Am I missing something?

We are V5R1 AS/400 mixed mode BPCS 405 CD Rel 2 with mountain of Y2K BMRs.
