#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.
