Query the ON-hand Quantity at spacefic time

Question

hi all
i'm a new to oracle apps
please keeptrack with me the following scenario of transactions on an item(FIFO COST Method) on the mtl_onhand_quantities_detail table
at 30/08/2010 we make receipt to the item x to sub inventory 1 with quantity 22
at 31/08/2010 we make receipt to the item x to sub inventory 1 with quantity 29
at 04/08/2010 we make receipt to the item x to sub inventory 1 with quantity 13
Now if we query the onhand to that item on 04/09/2010 will get 22+29+13 = 64
at 05/09/2010 we make sales order with 3 quanity for this item and make pick release for it from sub inv 1 to stage sub inv now the mtl_onhand_quantities_detail table is like as
30/08 19 for subinv 1
31/08 29 for subinv 1
04/09 13 for subinv 1
05/09 3 for subinv Stage
now i want to get the status of on the onhand for this item at 04/09/2010
by logic at this time i have 22+29+13 = 64
if i make the summation till that day it will decrease 3 from the onhand although i pick the 3 at 05/09
i want a query to get the onhand at 04/09 to result 64 how can i get it?
and if i make order for all quantities for this item and ship confirm it then the table will contain the quantity 0 for this item how can i get the hostirical quantities
thanks ?

Answer 1

You can get historical quantities by adding up quantities in the mtl_material_transactions table.
select sum(transaction_quantity) from mtl_material_transactions where transaction_date < '05-Sep-2009' and organization_id=&org and inventory_item_id=&itemid
If you don't have index on the transaction_date field, this query will be inefficient. So if you have to do this query multiple times a day, you may have to create an index.
Hope this helps
