Analyse Sales Item does not reconcile to Sales, Inventory showing more than 3 digits

Hi

The Analyse Sales Item report does not reconcile to the Sales Report, even though all sales are Item Sales, and via customer cards. The Sales in the GL is correct, but via inventory isn't.

Also, my inventory is showing bulk items with several decimal places. These are items used to built products, but also sell directly. 

can a script be run to fix this issue?

Thanks in advance

Donna
