Hi,
This can be done via the 'Correct' function in the Difference Analyzer. Corrections will create a new physical inventory document automatically. Please see below document for more details:
Difference Analysis - SAP Extended Warehouse Management (SAP EWM) - SAP Library
However, this function needs to be activated at a warehouse number level via the following IMG path:
Extended Warehouse Management -> Internal Warehouse Processes -> Physical Inventory -> Warehouse-Number-Specific Settings -> Specify Physical-Inventory-Specific Settings in the Warehouse
If this is not activated, correction is not possible.
