Condition type in Purchase Order

Hi,

I have a scenario in which I am paying extra money to vendor other than material price in PO.

Is there any condition type in SAP for Expeditory charges?

For a now I have created z condition type but in this scenario extra amount is debited on inventory-

e.g. material price is 100 and extra 20 then a/c entries in migo are-

inventory-120 debit

GR/IR-100 credit

G/L a/c for extra amt-20 credit

Price indicator for material is moving so extra amt hits material.

But I wan inv-100+

GR/IR-120-

G/L a/c for extra amt-20+

what chages I need to do?

Can anyone guide on this.

Thanx.
