What is the recommended approach for migrating 300 partially complete production orders while ensuring that the final inventory valuation automatically includes pre-go-live WIP costs without requiring manual revaluation activities at production order completion? Journal opening balances for WIP and then revaluing the finished good item so that COGS is correct for 300 prodn orders is very manual and prone to high levels of error. Also, a journal is required to manually portion an amount from wip to finished goods.
If all this is done manually on 300 orders then the risk of omission of a step or the process is high.
Any solid recommended approaches?
