This article provides information on sharing documents for review using Microsoft Excel 2002 software. Before sending a workbook for review, you must share it and turn on the tracking function. Turning on sharing or tracking turns on the other, in order to do each, you should choose Tools and Share Workbook. Then on the Editing tab, select Allow Changes By More Than One User At The Same Time. On the Advanced tab, adjust how many days changes will be saved. Set it long enough to let the file circulate and return to you, with enough time to review changes before they're discarded. Head to the Tools menu to set up the sheet to record changes everyone makes during the review process. Select Track Changes and Highlight Changes. In the dialog box, select When. Turning on change tracking also turns a workbook into a shared workbook. Ship the document off for review by others either by sending them the file as an attachment or by sending a link to the file stored in a shared location on an office network. When someone gets a document for review, he or she can click the attachment, make any changes, and then click Reply With Changes on the Reviewing Toolbar. To accept changes one by one, choose Tools, Track Changes, and Accept or Reject Changes. Excel will bring each change to the screen, letting you decide whether to accept or reject it.
