It gives better control over transactions if one decides to handle all
transactions.

I think it fails because it interprets numeric (18, 0) as
TFMTBCDField (or whatever it is) instead of TLargeInt.

No they still haven't fixed it. I complained to them and all I got was
a workaround (was never happy with that), but it still failed while
