Why FLOAD does not support multiset tables??
Answers were Sorted based on User's Feedback
Answer / adi
Fload will allow multiset table. But there is no advantage
of loading multiset table using fload, becuase fload does
not insert duplicate rows. If we try to load multiset table
using fload with duplicate rows, they fload inserts
distinct rows into the target table and the duplicate row
count displayed under second error table.

Fastload utility does not support duplicate rows.
1.Since MS table supports dup rows fastload cannot load MS
table.
2.Restart logic is one of the reason. Fastload is one of the
utility which loads data in blocks(64K). During restart
Fastload sends some of the rows for the second time which
occur after a checkpoint. Due to this Fastload rejects
duplicates.
For example consider 20 rows to be loaded in a table. FL
utility is used to load the table and ckpt is 5 rows. If
restart occurs after 7th row FL may send 6 and 7th to AMPs
during the restart. This records would be considered as
duplicates and rejected.
