Question: Why Opening Balance entry for the Serialized and Batch Item cannot be updated via Stock Reconciliation?

In the ERPNext, stock level of a serialized item is derived based on the count of Serial Nos for that item. Hence, unless Serial Nos. are created for the serialized item, its stock level will not be updated. In the Stock Reconciliation Tool, you can only update opening quantity of an item, but not the Serial No. and Batch No.

Step 1: New Stock Entry

Stock > Stock Entry > New

Step 2: Select Purpose

Step 7: Update Item Valuation Rate

Update valuation rate, which will be per unit value of item. If different units of the same items having different valuation rate, they should be updated in a separate row, with different Valuation Rates.

Step 8: Difference Account

As per perpetual inventory valuation system, accounting entry is created for every stock transaction. Double entry accounting system requires Total Debit matching with Total Credit in an entry. On the submission of Stock Entry, system debits Warehouse account by total value of items. To balance the same, we use Temporary Opening account as a Difference Account.

Step 9: Save and Submit Stock Entry

On submission of Stock Entry, stock ledger posting will be posted, and opening balance will be updated for the items on a given Posting Date.
