Blocking Base Exceptions

The exception combination that contains the most platform time should be used in the blocking process so that as many trips as possible are blocked as the system performs its first attempt at blocking the trips (in automatic blocking).

The exception combination that contains the most platform time is usually considered the base exception.
  1. In the Blocking screen, click Blocking > View Options > Exceptions.
    The Exc column appears to the right of the Frz (Freeze) column.
  2. Press F3.
    The Set Mode dialog box appears.
  3. Select the appropriate exception combination as the base exception.
  4. Click OK.
    The trips with exceptions that are compatible with the selected exception combination in your current context appear in the Unblocked grids.

  5. Proceed with blocking the trips according to your normal practice.
