Depreciation Close Status
You can run the Depreciation Close process only in an open period. You use the Business Unit/Book Definition page to determine which accounting periods have been closed. Select Depreciation Closed List to display all closed periods.
Note:
Open and close accounting periods are maintained in General Ledger and migrated with the financial subsystems. Each subsystem application can either use the periods that are created in General Ledger or update the open and close periods at the application business unit level.
