When you have assigned an item charge and posted the document, the cost of the item charge is posted to G/L accounts and linked to the item ledger entries.
You can find the posted item charge in three different windows, depending on the information that you want to find about the item charge. You may want to:
See the item charge as a G/L entry.
See the item charge as a value entry.
See the item charge from the item ledger entry.
The following procedure describes how to find the posted amount in the G/L accounts. The same procedure can be followed for item charges posted from a purchase document and for item charges posted from a sales document.
Open the 
Posted Sales
Invoice window if the item charges were posted from a
sales document.
If the item charges were posted from a purchase document, Open
the Posted Purchase
Invoice window.
Browse to the invoice you want.
Click Navigate.
From the list that appears, select G/L Entry and click Show. The General Ledger Entries window appears.
In the General Ledger Entries window, you can see the amounts that were posted to the general ledger accounts when you posted the invoice.
The account that the item charge is posted to depends on the general posting setup.
When you set up the item charge number that you used for the sales invoice, you attached the item charge number to a general product posting group and a VAT product posting group.
Those posting groups must be linked to a G/L account in both general posting setup and VAT posting setup for each combination of product and business posting group that you intend to use this item charge number with.
