Expenses Included In Valuation (value added in Income)

Dear I am very New in ERPNext,

I have installed Self hosted ERPNext,

We have bit confusion in Accounting in Expenses Included In Valuation ,

While making an Stock Entry there is an Difference amount, that is reflected in (Expenses Included In Valuation),

And Landed Cost Vouchers are also same, which is affected in P and L account, as negative balance of Expenses Included In Valuation.

To update valuation rate, below accounting entries are passed:

By Stick A/C Dr
To Expenses included in valuation rate Cr

You have to pass journal entries manually for landed cost as below:

By Landed Cost (e.g. Freight) Dr
To Cash/Bank/Supplier Cr

So the final effect in P&L would be zero.
