Task 3. Edit the Expression Rules

In this task, you make the expression rules reusable and available to all Analyst tool users.
    1. In the Column Profiling panel, verify that the FirstName rule is selected.
    2. From the Actions menu, select Edit > Column Profiling Rules.
    The Edit Profile dialog box appears.
    3. Verify that the rule is selected.
    The rule information appears in the bottom pane.
    4. Click the Edit icon.
    5. Select Save as a reusable rule in.
    By default, the Analyst tool saves the rule in the current profile and folder.
    6. Click OK.
    7. Select the LastName rule, and repeat steps 3 through 6.
    8. Click Save.
    Any Analyst tool user can use the FirstName and LastName rules to split a column with first and last names into separate columns.
