You have the option to update transactions in the Outbox folder before sending them to your trading partner. Note that the transactions under the Inbox, Received, or Sent folders are viewable but cannot be edited.
To edit a transaction:
Select Transaction Manager > Transactions on the Foundry Menu to launch the Transactions workspace.
Choose the Outbox folder from the Folders menu.
Double-click on the transaction to be edited or select Transaction Details from the View dropdown control. This opens the transaction details of the selected record.
