> I think OpenERP raw material consumption could be considered backflushing

Hi Eric, I don't think that is quite right.

From all the various descriptions I have read (mainly SAP), backflush 
allows the manufacturing order to proceed without waiting for particular 
stock items to be available, but it is checked and managed at the end of 
the operation.

So to my mind in OpenERP speak, it is a bit like having a product 
treated as temporarily "Consumable" until the manufacturing order is 
completed, then it is treated like a stockable product again.

From Production, Planning and Control with SAP ERP:
"
Backflush:

The BOM for the material to be produced specifies what quantities of 
which components are required for production. In repetitive 
manufacturing, not every goods issue is recorded at the same time as the 
physical withdrawal of the material from stock. Usually, component usage 
is automatically posted only when the finished product is received 
(backflush).
"

From the looks of what I have read, in SAP you can set a product, a BoM 
or a complete assembly as backflush.

"Backflush accounting is when you wait until the manufacture of a 
product has been completed, and then record all of the related issuances 
of inventory from stock that were required to create the product."
