Tally ERP Version - charging to inventory

Hi Friends..

In Tally ERP version, the purchases and direct expenses (like handling charges, commissions, additional materials) were entered separately,

because using landed cost per unit caused rounding differences affecting creditors' account.

How can i charge the direct expenses to the inventory now?

Pls give ur guidance. I am having the details of the expenses for each purchase.

(Nature of industry is marine export - if it is relevant)

Thanks and regards
