You MUST retrieve the JV from your Inbox. If you work on Atlas, the rejected JV will have a red X mark on the right under status, click on that JV to open the JV for changes. Make the appropriate changes, and then click Continue to send the JV back to the VPF. If you click Cancel, the JV remains in your Inbox. If you work in SAP GUI, click on your SAPoffice: Inbox, and then double click on the JV you want to open and change. Make appropriate changes, and then click Document/Complete. SAP will also ask you if you want to re-submit the parked document for approval. Click "Yes." If you click "No" the JV remains in your Inbox.
