+To freeze an Account, go to Chart of Accounts, and edit an Account.

+# Fetching Data from one Document to Another
+
+**Question:** We track Customer's PO No and PO Date field in the Sales Order. To have these values fetched into Sales Invoice as well, we have inserted Custom Field in the Sales Invoice. However, when we create Sales Invoice from the Sales Order, Customer's PO details are not being fetched.
+
+**Answer:** When data is fetched from one transaction to the another transaction, then the mapping of data is done based on the field names. If two transactions have fields with the exact same name, then it's values are mapped.
+
+For example, if you want Customer's PO No. and PO Date to be fetched from Sales Order to Sales Invoice, then you should ensure that Custom Fields added in the Sales Invoice has an exact same field name as in the Sales Order.
+
+Sales Order (standard fields)
+
+<img class="screenshot" alt="Standard fields in Sales Order" src="/docs/assets/img/articles/fetching-1.png">
+
+Sales Invoice (custom fields)
+
+<img class="screenshot" alt="Custom Field in Sales Invoice" src="/docs/assets/img/articles/fetching-2.png">
+
+Since names for the Customer's PO related fields are same in the Sales Order and Sales Invoice, when creating Sales Invoice from the Sales Order, values in these fields are auto-fetched.

+# Email Error in Sending or Receiving
+
+In ERPNext, you can customize the Incoming and Outgoing Email Gateway. On saving an Email Account, ERPNext tries establishing a connection with your email gateway. If your ERPNext account is able to connect fine, then Email Account is saved successfully. If not, then you might receive an error as below.  
+
+<img class="screenshot" alt="Email Error" src="/docs/assets/img/articles/email-error.png">
+
+This indicates that using login credentials and other email gateway details provided in the Email Account, ERPNext is not able to connect to your email server. Please ensure that you have entered valid email credentials for your Email Gateway. Once you have configured Email Account successfully, you should be able to send and receive emails from your ERPNext account fine.
+
+Note: Your ERPNext account is connected with an ERPNext email server by default. If you don't want to use your own email server, you can continue sending emails using ERPNext email server, without any configuration required in the Email Account.

+# Delivery Note Negative Stock Error
+
+**Question**: When submitting a Delivery Note, receiving a message says that item's stock is insufficient, but we have item's stock available in the Warehouse.
+
+**Answer**: On submission of Delivery Note, stock level is checked as on Posting Date and Posting Time of a Delivery Note. It's possible that you have stock of an Item available in the Warehouse. But if you are creating back-dated Delivery Note, and if item was not available in the warehouse on the Posting Date and Posting Time of Delivery Note, you are likely to receive an error message on the negative stock. You can refer to the Stock Ledger report to confirm the same.
+
+If this is the case, you should edit the Posting Date and Time of a Delivery Note, and ensure that it is after the Posting Date and Time of item's receipt entry.

+# Item Valuation Methods and Transactions
+
+In ERPNext, Item's stock valuation is updated on the creation of one of the following transaction.
+
+1.  Purchase Receipt
+2.  Stock Entry of type Material Receipt
+3.  Stock Reconciliation made for updating stock opening balance
+
+You can select valuation method based on which item's value will be calculated. Valuation Method can be set globally for all the items from the Stock Settings.
+
+<img class="screenshot" alt="Download Backup" src="/docs/assets/img/articles/item-valuation-1.png">
+
+You can also set Valuation Method in the item master, especially when a valuation method for an item is different from the default Method.

+# Purpose of Stock Received but not Billed
+
+When purchased items are received, an accounts posting is done based on the value of the purchased items in the Stock-in-hand / fixed-assets account. When you sell and deliver those items, an expense (cost-of-goods-sold) is booked, equal to the buying cost of the items. 
+
+As stock balance increases through Purchase Receipt, Warehouse account is debited and an adjustment account called **Stock Received But Not Billed** account is credited. At the same time, the negative expense is booked in account **Expense included in Valuation** for the amount added for valuation purpose, to avoid double expense booking. 
+
+On receiving Bill from the supplier, you will make Purchase Invoice against a Purchase Receipt. Here **Stock Received But Not Billed** account is debited, hence nullifies the balance in the Stock Received but not Billed Account.
+
+The balance in the Stock Received but not Billed account indicates the value of items for which Purchase Receipt has been made, but billing is pending.
