PRC: Interface Supplier Costs with Receipt Accruals

To interface Receipt Accruals when you run PRC: Interface Supplier Costs, what are the steps involved?

I understand from the documentation that 'you must set the Accrue Expense Items option on the 

Purchasing Options to Accrue at Receipt.' in order for the Receipt Accruals to be interfaced to PA.

Are there any other steps to be performed in Purchasing before Accruals are eligible to be interfaced to PA when you run the PRC: Interface Supplier Costs with Interface Receipt Accruals to Yes?

I also have read from Projects documentation that ‘you create sub ledger accounting for the receiving transaction in final mode’ in Purchasing before Receipts Accrual can be interfaced to PA.
