Generic Item Schema Review
--------------------------

                 Key: OFBIZ-562
                 URL: http://issues.apache.org/jira/browse/OFBIZ-562
             Project: OFBiz (The Open for Business Project)
          Issue Type: Wish
          Components: product
            Reporter: Chris Howe
            Priority: Minor


The current data model treats inventory item and fixed asset as if they have 
nothing in common.  And because there is nothing generic binding the physical 
item they have even been separated into the notion that the fixed asset 
physical item is dependent on accounting and the physical inventory item is 
dependent on product.  There is a bit of confusion because of the naming of the 
entities. 

Of course fixed asset is an accounting term, however I believe the accounting 
data model has overstepped it's role on the physical item.  Applications that 
have to do with accounting should have no concern on whether the fixed asset 
was moved from storage area A to facility B, as long as ownership hasn't 
changed.  Likewise accounting shouldn't be concerned on when the last time the 
item classified as a fixed asset was washed or serviced (however it should be 
concerned with the charges for those washings and services)  In business these 
departments that take care of these things are different.  The dock workers 
care about what isle the item is stored at; the maintenance department cares 
about the servicing of the equipment; the bean counter is only concerned about 
the depreciation of the item and the receipts.  

Because the physical item classified as the fixed asset is an accounting data 
schema, the product entity depends on accounting.  This should not be.  Because 
the physical item is in the accounting schema, manufacturing is now dependent 
on accounting.  This also, should not be.  This model prevents Apache OFBiz 
from supporting the rental of items as well as modularization.  Both are 
features that would greatly enhance the value of Apache OFBiz.
