I´m new in odoo and I have a doubt...

I have the "A" product whose BOM is:

B

C

where "C" is purchase product but "B" y a Semi-finished product  whose BOM is:

D

where "D" is a purchase product.

Well... If I don´t have enough stock of any of them, I want that when I make a MO of "A" automatically  Odoo suggest ( or make) a MO of "B"... is it possible at Odoo standard or I have to develop this action?
