ICWHIL was removed from the delete loop. This is due to key number 0 no longer being ordered by company+item+warehouse. Since key number 1 of ICWHIL does have that order, key number 1 is used in FACTS 9.3.0 to delete and perform the delete from ICWHIL, as was done prior for ICLEDG.
During an upgrade to FACTS 9.3.0, ICWHIL checks for matching company+warehouse+item records in ICWHSE. If not present, that ICWHIL record is purged and not brought forward into FACTS 9.3.0.
