Odoo has only 3 move types:

• In (Getting Goods): When processed from 'Incoming Shipment' menu
• Out (Sending Goods): When processed from 'Delivery Order' menu
• Internal: When processed from 'Internal Moves' menu

You can get your reports by playing with filters under:

Reporting > Warehouse > Move Analysis

Reporting > Warehouse > Inventory Analysis

If you find moves with transaction type called 'Other', it means the move have been processed from 'Physical Inventories' menu and not from the ones mentioned above.

Hope that helps
