I am using site administrator user account to perform deletion, please advise on any suggestion I should follow to resolve the problem.
Item withdrawal is working fine but not exact solution as we will loss stats on item that only bitstream should be replaced.
If there is more needed please let me know I will share on this problem so that it can make clear sense.
