The purpose is to rebuild the indexes after importing the data which is faster 
than updating the indexes while importing the data.

Joel,

It will work but will not give you any performance boost. Even in 12c I have 
not seen any tweaks to make this happen automatically in IMPDP. EXPDP and IMPDP 
will obey settings on objects "as is" which is the beauty (and a curse when we 
do remap for plsql code). So, you must take manual steps if you want to enhance 
the performance of indexes and constraints while performing impdp.

For this scenario can you not just impdp the tables, then impdp a second time 
for everything except for the tables?
