Odoo is the world's easiest all-in-one management software. It includes hundreds of business apps:
CRM | e-Commerce | Accounting | Inventory | PoS | Project management | MRP | etc.
[V7] I need help understanding the way BoM's are stored in the database. Why are multi-level BoM's stored in the same table as regular BoM's?
I would like to discuss with people who have worked in openerp with mrp about the logic of databese structure of the mrp_bom.
I can't see one reason to make mrp_bom a 'flat database table' . I really can't.
It is nearly impossible to make even a little complex like bom and be able to know what is going on. What I mean by that is a bom that consists of other bom that consists... multi level. There is no way to know which bom enters the original product.
Am I missing something or what?
The database represents only the persistence of 'simple' data related to an Odoo object/model. Most of the time you need to review the Python definition of the class to understand how the tables represent a logical object that may not have all the information stored in the database. All tables in the database are related to others.
BoM's are stored in the mrp_bom table and BoM Lines are stored in the mrp_bom_line table.
Using both tables, it is easy to see which BoM is the 'parent' and which are the 'children':
