The cancel button does not simply cancel the recent changes you’ve made to a maintenance document or revert to a previously-saved version, but instead it cancels the ability to submit the document to workflow and route it for review and approval.  You can copy a canceled maintenance document to a new document number that essentially moves your work from the canceled document to a new one.

You are no longer able to route or submit this document.  However, if you want to preserve data entry/selection and/or attachment work from this document, you are able to copy it.

For information about copying a maintenance document, see “Copying A Maintenance Document”.
