Small index will not be compressed - In the output log for compression

Hi,

while doing compression all the table objects and most of the indexes are got compressed except like more than 255 columns, already sap compressed objects, few exceptional static tables.

But there was huge no of Small indexes are not getting compressed why ??? is it coz of candidate for considering object to be compressed depends on size of the objects as well.(min it should be

more than some MB etc..).

coz, when we analyze the logs,it has more than 80% of objects are not compressed warning since small index will not be compressed ..

Please provide your wise ideas/tricks handle above scienorious.
