Hi,
When create a new InventoryItemDetail the InventoryItem will be updated by eeca. But If two threads create InventoryItemDetails simultaneously. Because we use ReadCommitted Isolation level, Neither will see InventoryItemDetails created by other threads before transaction commit.
updateInventoryItemFromDetail service will get incorrect qoh, and InventoryItem will be updated. Two threads will all be committed successfully.
I can confirm the behavior by set a breakpoint in org.ofbiz.minilang.method.entityops.StoreValue.exec(MethodContext) to emulate above process. The result can be checked by this SQL.
select * from inventory_item t1 left join (
select inventory_item_id, sum(quantity_on_hand_diff) as qoh, sum(available_to_promise_diff) as atp from inventory_item_detail
group by inventory_item_id) t2 on t1.inventory_item_id = t2.inventory_item_id
where t1.quantity_on_hand_total <> t2.qoh;
