We ran into a problem with shop orders that did not get purged by CST900 
because CST900 looks at inventory history on a shop order as part of the 
process of deciding whether or not to purge - conclusion = however old your 
shop orders are, you do not want history retention to be LESS than that.

BPCS/36 had an option to restore from INV900 tape some prior history & then 
run INV history reports with choice of old stuff only or include on-line 
history --- I have not seen that option on BPCS/400.  Did SSA take it out?  
We rarely used it because it was a royal pain figuring out where the data was 
that we wanted to access, with 12 backup sets per year & poorer tools for 
accessing off-line meida than are available today.  If copy to tape was less 
often in the year, this sort of thing would be more practical, inspiring more 
attention to archiving.

BPCS/36 in addition to how many days keep inventory also had minimum history 
to keep on any one item - I have not seen that option on BPCS/400 --- we set 
like 3 minimum records so that inactive stuff from physical to physical would 
have last year's physical records & not much else, or even 2 physicals ago.

We also had a modification on BPCS/36 that when the INV900 copied records to 
tape, we also captured a particular kind of record that some folks wanted to 
trace in perpetuity.
