Cost History

Another dumb question.

If you look at some item in INV300 F21 filter on "#" you"ll find audit tril
of changes to costs.
I had thought that any time anyone changed BPCS costs, other than through
some blanket program like CST600 or CST900, that created an "#" audit trail
of the changes.

However, I have recently had occasion to be going into CST100 & other places
to fix some costs ,,, thankfully not very many negative costs, but we also
got too many where the cost buckets not adding up right (they are off close
to 0.00001 so I suspect BPCS rounding.).  To my surprise my corrections to
actual costs did not get into the history showing what items I had changed.

Is that because INV150C has "#" actual cost Y/N blank?
or is there some BPCS rule about what kinds of cost changes actually go into
the history?
