Tvm.checkopt just indicates if there will be duplicate row checks. A MULTISET table with a UNIQUE index simply doesn't require those
checks.
If you add a unique index to a multiset table, checkopt will change to 'N' and if you drop the USI or alter the UPI to NUPI, it will be change
back to 'Y'.
Btw, Merry Xmas :-)
