[Subodh deshpande_1]

Hi all,
i am performing user managed TSPITR. i was able to recover the auxilliary instance but however while transporting the tablespace i got the following error

i have put the tablespace in read only mode and also checked TRANSPORT_SET_VIOLATIONS table for any violations. it says no rows selected. but still i m getting this error.

Any quick help will be highly appreciated.

Thanks & Regards
