Hi,
Please provide more information here.
Depreciation normally flows to product costing either directly (from depreciation charged to a production cost center) or indirectly (via an assessment to the production cost center). The production costs are then abosorbed into the production order at a standard activity rate. There is then an over/under absorption of production costs which are transferred to the production order, CO-PA (via an assessment) or to the material (if you use material ledger).
Regards
