You use the Field Edits tab to undo one or more field operations (such as move, split, join, create using text, or create using join).
The columns of the Field Edits tab display information:
Operation—Types of operations, such as move, split, join, create using join, and create using text
Columns—Number of columns in the rules file that will be moved, split, joined, or created
Split Characters—Number of characters in a split operation
You access the following dialog boxes by clicking the relevant buttons. For example, if you click the Move button, the Move Field dialog box is displayed, and, if you click the Create Using Text button, the Create Using Text dialog box is displayed.
To delete operations, you select an operation, and click Delete. You must delete operations in reverse order; that is, you must delete the most recent operation first.
