Export return order, undo shipment

pashya1972

Hi,
In Localisation EXIM module which i think is addon. I m facing following issue.

We need to cancell Posted Export Invoice by way of return order however in EXIM there is no such provision. If i want to reverse all the effects of export sales, shipment then what is the procedure through which i can reverse all the effects.
1.RG Register QTY
2.RG Register Value
3.Item Ledger entries -QTY/Value
4.Interim accounts ,COGS etc effects.

Pls note in EXIM module all the entries r required to be entered in Foreign Currency and since no cancellation/reversal method is available.

Thanx in advance
