You can review any of the changes you’ve made in your plan using the plan Activity Log. The Activity log can be sorted by date or change type, and it can be exported so that you can review the changes in an Excel format. If desired, you can also export your plan into a PDF or PPT and include a graphical depiction of the Activity Log, so that you can see a summary of the proposed changes on each page.
