Setting up the workbook for the approval process
You can set up a workbook to support the Approval process. Unlike other workbooks, a workbook that supports the Approval process includes a special status area above a view that is used for specifying data that will later be submitted for approval. This status area indicates whether the data is submitted for approval (or not), submitted and approved, or submitted and rejected. The status of the data determines whether the data is writable or is locked for write-back.
Moreover, unlike other workbooks, a view allows write-back only for users who are defined as submitters in the Approval process and then only when the status indicates that the data is either unsubmitted or rejected. The workbook is read-only for all other users and for any other status.
