How to enable Audit Log for Sales Order in Order Management ?

Hi Guys,

We wanted to enable audit log for all the transactions related to Sales Order and shipping in Order Management.

We tried following the basic information available but did not achieve the result.

steps followed- ''Setup and Maintenance » Manage Audit Policies » Configure Business Object Attributes » Select Order Management

 as the product, choose the specific business objects and attributes you want to audit, and then click save and close.''

But here we are not able to see the Order Management as product.

second Under sales Product there is not attribute to add.

Is there any document which I can follow for Order Management Audit log which refers to the entire transactional audit related to the sales and shipping?
