Both TBDEDataSet and TIBCustomDataSet (in IBX) have a property called
UpdateRecordTypes, which you can set to enable showing of
deleted records, but I can't find an equivalent in IBO.

I am doing an Inventory program, in its simplest form, it has three
tables: Item, ItemTr, ItemTrDet.
-Item keeps the item information and current balances.
-ItemTr(master) and ItemTrDet(detail) keeps the in and out activity
of the items.

I want to update the balances whenever the user changes ItemTrDet.
When the user insert some records that issue some items, the program
will reduce the balances for those items.
At a later time, if the user delete some records, the program
must increase the balance back for those items.

That's why I want to walk through deleted records, so that the program
can count the balances correctly.
