MS has indicated that the posting has changed in AX2012. Here is the explanation provided:
When a product receipt is recorded for a stocked item, two accounting processes take place:
ï‚· One accounting process creates an accounting entry for the accrued liability. The accounting entry amount is for the received quantity of the stocked item, multiplied by the currency amount per unit for the purchase order. This process uses the new accounting framework that was added in Microsoft Dynamics AX 2012. In the following example, XX denotes the currency amount of the accounting entry.
Debit Purchase expenditure, un-invoiced XX
Credit Purchase, accrual XX
ï‚· Another accounting process accounts for the cost in inventory for the received quantity of the stocked item by crediting the expenditure ledger account and capitalizing the cost in an inventory asset ledger account.
Debit Product receipt XX
Credit Purchase expenditure, un-invoiced XX
When a vendor invoice is recorded for a stocked item and accounting entries are created, two accounting processes take place:
ï‚· First, the accounting entries on the product receipt for accrued liability are reversed. The amount that is reversed is based on the quantity of stocked item on the vendor invoice that is matched to the product receipt. Then, the accounting entry is created to record the liability for the vendor invoice. Both entries are created by the new accounting framework that was added in Microsoft Dynamics AX 2012.
Credit Purchase expenditure, un-invoiced XX
Debit Purchase, accrual XX
Debit Purchase expenditure for product XX
Credit Vendor balance (Accounts payable) XX
ï‚· Second, the accounting entry on the product receipt that records the inventory cost is reversed. The amount that is reversed is based on the quantity of the stocked item on the vendor invoice that is matched to the product receipt. Additional account entries are created to record the inventory cost under a new inventory ledger account classification.
Credit Product receipt XX
Debit Purchase expenditure, un-invoiced XX
Debit Purchase, product receipt XX
Credit Purchase expenditure for product XX
Conceptually, if you net the vouchers together, the effect remains the same as the accounting entry that is generated in Microsoft Dynamics AX 2009. Because two separate accounting
processes are used that do not interact with each other, it is not possible to summarize the vouchers together in Microsoft Dynamics AX 2012.
