Below method is existing in
Query 1:
**stock.move**
       

        @api.multi   

      def action_assign(self, no_prepare=False):
            for move in moves:
            if move.product_id.type == 'consu'               

                moves_to_assign |= move         

                continue      

           else:
                moves_to_do |= move

I just want to add one line changes (i.e)

         @api.multi   

def action_assign(self, no_prepare=False):
         for move in moves:
            if move.product_id.type == 'consu' or move.product_id.type == 'service':
                moves_to_assign |= move                continue            else:
                moves_to_do |= move

  I just want to customize only this line
      **if move.product_id.type == 'consu' or move.product_id.type == 'service':**

and also **Query 2:** **'mrp.production'**

in this method
    def _generate_raw_move(self, bom_line, line_data):

I just want to remove the below line      

    if bom_line.product_id.type not in ['product', 'consu']:
            return self.env['stock.move']
