Paul Foxworthy commented on OFBIZ-9464:
---------------------------------------
Hi Vaibhav,
I think the two are independent of each other. You might use FIFO for
inventory, to minimise customers getting old and stale stock, but LIFO for
accounting, to ensure you get a higher amount into your Cost Of Goods Sold
account.
The whole point of COGS_FIFO and COGS_LIFO is that for a given inventory item,
the quantity for the purposes of *valuation* of stock can vary from the
quantity of *actual* stock. In contrast, the inventory reservation sets a
policy on which inventory to reserve for an order. You are reserving actual
stock from an actual inventory item in an actual place in your warehouse.
createAcctgTransForSalesShipmentIssuance looks for other inventory items for
the same product, and may adjust the accountingQuantity on them, and not the
accountingQuantity for the inventory item that was shipped.
I think all that's necessary is to split out the part of
createAcctgTransForSalesShipmentIssuance that deals with adjusting accounting
quantity, and use it for your transfer service as well.
Hope that helps.

> Project: OFBiz
> Issue Type: Bug
> Affects Versions: Trunk

> Assignee: Vaibhav Jain
> Labels: inventory, stock, valuation
> Fix For: 16.11.04

>
> when we transfer inventory, the accountingQuantityTotal field of
> _InventoryItem_ entity is always ZERO. There is no reflection of ATP/QOH in
> accountingQuantityTotal.
> This will create following issues in the system.
> # Accounting quantity total will mismatch with the original quantity in the
> facility which shows the wrong result when we calculate facility specific
> inventory valuation.
> # Inventory reservation also throws an error in some specific case like when
> AQT of respective product is zero in the specific facility from when
> reservation happens.
> As we manage 5 different statuses of inventory transfer in OFBiz and
> according to my current understanding these processes are associated with the
> respective statuses, which are as show below
> Requested: As inventory transfer is requested for another facility.
> a)ATP, QOH and AQT should decrease from the inventory item of From Facility
> and QOH of To Facility should increase.
> b)ATP and AQT should be Zero in To Facility as inventory is not transferred
> yet. But QOH should increase at To Facility because QOH shows the
> xferquantity later. At the time of the completion of the transfer
> ATP = ATP + (QOH - ATP) (Adjustment in case of backorder)
> AQT = QOH
> b)AQT should not decrease because AQT is used for accounting purpose and as
> of now quantity is still in From Facility as the transfer is not done yet.
> which shows the xferQuantity later
> Scheduled: As inventory transfer is Scheduled for another facility. ATP, QOH
> and AQT should not affect in both From Facility and To Facility.
> En-route: As inventory is routed to reach at To Facility. Even in this case
> ATP, QOH and AQT should not affect in both From Facility and To Facility.
> Complete: As inventory transfer is completed
> a)ATP, QOH and AQT should not affect at From Facility.
> b)QOH will be same but ATP and AQT should affect respectively
> ATP = ATP + (QOH - ATP)
> AQT = QOH
> Cancelled: As inventory transfer is cancelled and inventory item record is
> already created so
> a) ATP, QOH and AQT should decrease from old inventory item and ATP, QOH and
> AQT should increase in the newly created inventory item.
> Key points:
> If the whole ATP and QOH is moved then new inventory item will not create.
> Only Facility and location are changed for existing inventory item.
> Before Changes:-
> As I know there are following processes are associated with respective
> statuses
> **Note: ATP-> Available to promise QOH-> Quantity on hand AQT->
> Accounting quantity total
> 1. Requested:-
> ATP =0 QOH=Transferred quantity
> AQT=0
> 2. Scheduled:-
> ATP =0 QOH=Transferred quantity
> AQT=0
> 3.En-Route:-
> ATP =0 QOH=Transferred quantity
> AQT=0
> 4.Complete:-
> If the partial quantity of any inventory item is transferred.
> ATP =Transferred quantity QOH=Transferred quantity AQT=0
> If the whole quantity is transferred then only facility id and location
> will change no new inventory item record will create.
> 5.Cancelled:-
> No new inventory item record will create. An inventory transfer record is
> created with whole ATP/QOH in cancelled status.
> After Changes:-
> As shown above, accounting quantity transfer will not affect in transfer
> inventory. After the following changes, records will be updated a shown below.
> 1. Requested:-
> ATP =0 QOH=Transferred quantity
> AQT=0
> 2. Scheduled:-
> ATP =0 QOH=Transferred quantity
> AQT=0
> 3.En-Route:-
> ATP =0 QOH=Transferred quantity
> AQT=0
> 4.Complete:-
> If the partial quantity of any inventory item is transferred.
> ATP =Transferred quantity QOH=Transferred quantity
> AQT=Transferred quantity
> If the whole quantity is transferred then only facility id and location
> will change no new inventory item record will create.
> 5.Cancelled:-
> No new inventory item record will create. An inventory transfer record is
> created with whole ATP/QOH in cancelled status.
