Thanks a lot. We will try to see if we are lucky enough and are hitting the first one i.e. bug related to APPEND hint (i.e. related to bad rowid) and that can be passed though if we would be able to do that load manually using conventional load method . And hopefully, when it says about a bad rowid, it's for the source table from which it's picking data from and not the one to which it's loading data to. And that source table is smaller one though that is also partitioned and having bitmap indexes on that. But yes , if this works then, subsequent loads should not fail as those will not pick the same bad rowids from the source table again.

Regards
Lok
