Receipt Accounting vs TAB configuration

Content

HI,

in the Purchasing module I configured the TAB accounting and defined all my accounts. For example, the Inventory Account in the Mapping set (when we ship the item to the Inventory Organization, system generate the Inventory Account). a second definition is the Accrual Account

But, in Cost accounting, we need to define again the Inventory Valuation.

In the Receipt Accounting we need to define the Accrual and Inspection account.

Is that correct? I need to define the same account in multiple places?
