The job ledger entries are the only one so important ledger that is not possible to be reconciled within the periods in the item's costs area. System is always just overwriting the item cost on the initial job ledger entry with the actual cost coming from all the linked value entries and is losing the history of how the cost has been changing over time. In other areas there is usually the detailed ledger that is keeping the whole history of the value change. For example an item ledger entry has related value entries that are establishing its cost, customer ledger entry has a customer detailed ledger entries that are tracking its LCY value and application, the same for vendors, fixed assets also are reconcilable with the G/L when analyzing the period by period. So my feeling is should be changed so that the “Job” module follows the natural Dynamics logic in this matter.
