How Reverse ML Document to Nullify the A/c posting

Hi All Need a urgent help on the below issue.

Taking out all the items in inventory module to be transferred to warehouse module. However, during the process uploading, they only reconcile the IDR(Local currency) balance, while there is mismatch in USD amount between those that have

been taken out and those that have been put back. From what we can see, when they put the inventory balance back, the currency used was USD exchange rate that applied on that date rather than the original exchange rate from original transaction.

What we found this Exchange difference create ML Documents.

So How can we reverse this mismatch USD balance.

Need a quick help.

Thanks in Advance

Regards

Ajit
