Hi All, 

we are currently struggling getting our material flow implemented for a semi-finished good. The Odoo documentation together with Odoo AI and ChatGPT is just not helping due to inconsistent answers. 

Find the link to the flowchart in the first comment. 

We are responsible for managing the raw material at Vendor A which supplies Vendor B. We are responsible for the POs towards both vendors and must understand the stock level of the raw material (RM) at Vendor A and the post-processed material (DY1) at Vendor B.

Vendor B does not talk to Vendor A. 

When BOM Item 1 (semi-finished good) is low at WH/Stock the PO shall be created towards Vendor B. 
POs towards Vendor A shall be automatically created if stock level at Vendor A low after receiving Item 1 at WH/STOCK.

PO to Vendor A shall consider RM stock when placing PO for DY1. 

However POs to all Vendors shall be created when re-order rule is triggered.

Can anybody help to understand the fundamental mechanism of Odoo to achieve:

1. the workflow can be achieved to get stock level deductions of materials used to produce Semi-finished good. 
2. stock allocated at right place
3. Vendor A delivers to Vendor B by default

Thanks in advance.
