Hey Vinod, Could the ID for that hold (reserve) be already present in old_reserves? If so, that error will occur when the item is actually checked out, I'm afraid, because the ID from reserves gets moved to old_reserves. The bug is documented here: https://wiki.koha-community.org/wiki/DBMS_auto_increment_fix And this was the way I personally handled it: http://koha.1045719.n5.nabble.com/Salvaging-data-before-using-DBMS-auto-incr...
