Not getting amount for bill of material items

Anyone know how to show the amount for bill of material of every item used, i have created the production order, and i have material available in inventory which i am adding in bill of material and the inventory revaluation price is set for each product . but after creating the production orders, i am getting these 2 problems:

  1. Why insufficient qty is displayed on the production order for every item.
  2. Not getting amount for each item that i am using in the bill of material. IDK where to mention their price so it fill show the total amount for the complete bill of material.

in this case you have not entered Purchase Invoice Item Price, Because system pick amount from Purchase Invoice or i other case you have created Journal enter for opening stock without debit value.
