Tracking Workflow Approvals
If your business has an approval process (perhaps for purchase orders, or contract approval), then you probably want to keep a record of who signs off and when.
Adding an append-only multiple-choice approval field to your application is a perfect way to streamline your process. Such a field can allow a series of people to leave an approval “stamp” on a record that no one else can fake, and by using an append-only field, you can ensure that previous approvals cannot be overwritten. This handy feature will allow you to see a complete history of a record’s approval status.
To get started on adding your approval field, first create a new multiple choice text field with a name like “Approval.” Edit the field, and set the Append Only option under Text Options to “Yes - Expanded Style.” You can leave all of the append options as they are.

If it is not set already, set the Data Entry type to “Multiple-choice,” and create a series of options such as “Approved,” “Rejected,” and “Postponed.”
Now, when editing a record, in addition to setting the approval status, you can view the complete history of other people’s actions.

Another use of append-only fields is to create a log of progress updates, where users can add entries that will be added to a list of all previous updates.
