Account determination is required for Opening and Closing Posting when configuring accrual types for the accrual engine.
This means that when performing opening and closing postings, the system needs to determine which accounts should be affected by the accrual.
Account determination is not required for Periodic postings as these are usually predetermined and do not change frequently.
