what permissions I need to grant for user to use "Manage Content and Structure"

I granted Contribute permission to users. I modified the contribute permission and checked override checkout and approve items. even after this modification users aren't able to copy or move documents from one library to target library. "Inadequate permissions to "target library" to complete this operation. Please suggest. Per Microsoft Contribute permissions is sufficient for this action. http://ift.tt/1GHDGiL
