Xestia Gelforn Help: Deleting a RFENote:
Deleting a RFE requires the Delete RFE permissions for each project you want to delete a RFE for.
Go to any page associated with the project (or click on Projects link from the menu at the top of the page and select the project you want to delete a RFE for) and click on the RFE link in the Project Links section. Select a RFE to display by clicking on the name of the RFE and click on the 'Delete RFE' at the top of the page.
A page then appears asking to confirm the deletion of the RFE. To confirm the deletion of the RFE click on Delete RFE.
Once the RFE has been deleted, it (and the RFE replies) cannot be recovered so please think carefully before deleting.
