ODOO11 MRP multiBom bad production planing

- 15/05/2018 23:36:29

I have a problem with mrp that I don't understand...

I have a product A, with a bom containing product B with routing R1

Product B has also a bom containing product C with routing R2.

Product C is a buyable product

if I confirm a Sale Order with product A, I have automatically 2 manufacture orders with R1 and R2.

But the problem is when I planify those MO, they start on the same date....

In reality, product B should be manufactured first and only then product A can be manufactured.

So in the Gantt view, we should have the MO planify with the proper order.

When I launch the planing, all manufacture order start at the same time...

Is there something I missed.

Thanks for your help it is a long time I'm searching ...
