Answer / vinay
Above all concepts require communication between Multiple
Amps.
As per Fastload and Multiload doesnot provide any
communication b/w multiple Amps and they Operate
Independently.
As concept is violating as well as it takes time to
implement the above operation they are not allowing them.

Answer / yuvaevergreen
Vinay is correct.
SI -
USI - generally stored in subtable in a different amp other
than the amp having data row. Both the utilities do not
support.
NUSI - The subtable is stored in the same amp itself. Mload
supports it and Fastload not.
JI -
TD generally stores the rows of join index across the amps.
Both the utilities do not support.
RI and triggers -
These are multi amp operations and any operation involving
communication between two amps is not supported by these
two utilities.

Answer / tdguy
USI,JI,RI and triggers involve multi amp communication.
Hence, both fload and mload dont these. But mload supports
NUSI alone as it is amp local.
