Why can't I edit the rate of an Item Receipt when receiving a Non-Inventory Item?

Answer/Solution:
 


Unlike Inventory Items where we record the value of the item as an asset at the time of Item Receipt, the cost of Non-Inventory items are only recognized as an expense (depending on the Expense Account entered on the item record) at the time of billing.

For Inventory Items, we are recognizing the increase on our Asset to record the cost of the item acquired during the receiving stage. However, for non-inventory items, we need to recognize the expense incurred for the acquisition only at the time when we are also recognizing the related liability incurred (Accounts Payable) - done during the Billing stage.


Note : This is only applicable when the Non-Inventory Item is set to Can Be Fulfilled/Received = T under Preferences tab of that item's record.
