Incomplete JIT backflushes

To all,

I have a situation here that occurs sporadically.  Items are submitted to be
backflushed and only part of the BOM is backflushed.  Most of the time,
there are no problems in backflushing these same items.  The JIT process is
used to do the backflush.  The shop order is created, the time ticket
entered and finally the item submitted for posting.

To try to understand when and why this is happening, I have added a short
program that checks whether for each FMA record there is a VLA record.  The
results are stored in an exception file.

The BPCS version number is 2.7, the operating system 3.2.  The client
modifications to the backflush process that were done pertain to the
assignment of the workstation ID.  In all programs called by the
backflush/posting process, the last part of the WSID is used instead of the
first.  This modification cut-down the frequency of errors.

Some of the users use Client Access. We tried to assign a workstation name,
but that name is disregarded on V3.2 of CA.

Another modification that was done to the entire BPCS system was the Y2K
correction.  That was done probably 3 years ago.  Other than that, the rest
of the code is as SSA delivered it.

I wonder if in subsequent releases of BPCS, there were any fixes to
backflushing.  Any ideas on how to deal with this problem, if not directly,
then indirectly ?
