Hi Muhammad Yousaf ,
You can check with below reports if available in AX 2012!
On hand inventory: - In this report, set the 'Warehouse' check box enabled and generate the report.

It will generate a report like this...

Physical on hand inventory: - In this report, select the parameter as per the following.

Once generated; report will give you below output.

As I mentioned; not quiet sure about AX 2012 but if these reports are available there, then you will mostly find these reports either in 'Inventory management' OR in 'Warehouse management' module.
Kindly check and update us in this forum.
Best regards,
Sourav Dam
