Production variance reval by inv close

In AX 2009, as a new feature, at the last step of an inventory close after settlement, it'll revalue production variances for ended work orders. This is the method that does the actual job: Class InventCostHelp > updateLedgerPosting, and I stripped the method comments:

Controls the last stage of the inventory closing.
In this stage the following things will be done:
- Production variances for ended production orders
- Indirect cost for open production orders
- ledger postings
- Creation of the inventCostTransSum records
- Final check against the prodTable

If you want to analyze the variances from the closing voucher, e.g. which prod orders generated the variances, you'll have to dig into the InventCostTrans and InventCostTransVariance tables, or check the IM>Inquiries>Standard cost transactions form.
