The workflow will depend on your internal processes but may follow a similar route to this:

	Transaction has been created (this is not visible to the corporate)
	Approval is required before sending the import transaction to the corporate (this is not visible to the corporate)
	Transaction is awaiting final approval to send to the client (this is not visible to the corporate)
	Transaction is now available for the corporate on their workbench
	Corporate has acknowledged the receipt of the export LC
	Corporate has acknowledged the receipt of the export LC amendment
