Hi Odoo Community,

I have many automatisations problems on Odoo and I would like to find a solution. 

I work in a company in which we produce several products with lots of variants and a short stock in the inventory. 

Knowing that our BOM for each product can change, I would like to know if there exists a code or a solution to get Odoo more dynamic.

1. When I modify a BOM for a component, I would like to modify any manufacturing order in any sale order automatically and not manually.  
2. When I modify a sale order, I would like that the Manufacturing order modify also by itself automatically depending of the modifications given by the customer. Sometimes the customer wants to change for example the color of the product, so we have to modify for the moment the Sale order and manufacturing order manually. 
3. Sometimes, we have to change the quantity of a purchased component. Odoo is dynamic when the quantity is higher than the original one. However, when we modify the purchase by changing the initial quantity with a lower quantity, it doesn't change by itself the IN/*** document automatically. 

If any one of you has some proposals or any solutions, please let me know.

Thank you for your help,

Best regards,

Louis
