#Valuation Based On' Field in BOM
**Question:** What do the various options in Valuation Based On Field in Bill Of Materials (BOM) Form mean?
**Answer:** There are 3 available options in the Valuation Based On field;
Valuation Rate: Item valuation rate is defined based on it's purchase/manufacture value + other charges.
For Purchase Item, it is defined based on charges entered in the Purchase Receipt. If you don't have any Purchase Receipt
made for an item or a Stock Reconciliation, then you won't have
Valuation Rate for that item.
Price List Rate: Just like you pull item prices in sales and purchase transaction, it can be pulled in BOM via Price List Rate.
Last Purchase Rate: It will be the last Purchase Rate value of an item. This value is updated in the item master as well, based on rate in the Purchase Order for this item.
