Comparing Host Screens and Screen Recognition Rules

Using the Screen Recognition Rule editor, you can view two host screens, and their screen recognition rules, simultaneously. This is helpful when two screens are so similar that auto-generated default recognition rules are not unique to each other.

To compare two host screens and screen recognition rules for both
  1. With the host screen you want to change selected and the Screen Recognition Rule editor open, choose the Recognition Rule page.

  2. In the Compare to Screen list box, select the name of the host screen to which you want to compare.

  3. Choose View.

    The Reference Screen Recognition Rule viewer appears, with the host screen and its screen recognition rule displayed.

  4. Compare the screen recognition rules for both screens.
    Note
    • You may need to resize the Screen Recognition Rule editor and the Reference Screen Recognition Rule viewer, and/or adjust their placement on your screen for side-by-side viewing and comparison.

    • Although you can view host fields, user fields, and sub rules on both host screens, you can make changes only within the Screen Recognition Rule editor — you cannot edit the reference screen.

    • No more than two screens can be compared at any time.
  5. Make a note of the differences you find — from the list of differences, you must identify which ones are true for only one screen (not all differences cause a host screen to be viewed as two or more screens).

    In most cases, deleting the problematic sub rule will resolve the problem. However, you should take into account other factors, such as completion rules.

    Note If you have difficulty locating the differences, copy and paste the screen recognition rules of both screens to separate text files, add a carriage return after each (AND or OR) operator, then compare these files line-by-line or using a text-comparison utility.
  6. When you have finished making your comparisons, from the Reference Screen Recognition Rule viewer, select Close.

    The Reference Screen Recognition Rule viewer closes.
