Imported Journal Entries - posted to 1935

Hi, 

Recently, one of our associates uploaded a journal entry to 1935. We were unable to edit or delete this journal entry. When I tried to book a reversing entry I received the normal error messages you would expect. The entry was able to be imported without any errors. Is there a way to stop entries that would normally result in alerts or would not be able to post from being imported? 

Thanks!

Mary
