In recent updates, we have adopted a new Operations engine. This allows Alexandria to give preferences to processes like Circulation, but means that reports and utilities may run a little slower. 

First, check your session overview and take a look at your Call Number Range. Make sure the "From" and "Through" fields have the same number of characters. 

1. For example From: 000.000 AAA

                                Through: 299.999 ZZZ

We recommend completing all of your inventory sessions when you are finished with your whole inventory. This will ensure any items that may have been misplaced on a different shelf to be found and scanned.
