Receipt Raw Material for Invoiced Sales Order

Dear All,

I need help,

my company has sales order, but some raw material are not received yet from vendor because our vendor has limited capacity to produce the raw material.

later our customer agree to be invoiced, some raw material will be sent later once ready.

sales order has been invoiced, my question is :

1. If my production order still started, altrought the sales order has been invoiced. then once the raw material receipt from vendor, will the cost impact/flush them back?

really need your advice.

Thank you
