Viewing and modifying action schedule in the scheduling table

The scheduling table displays the timing information (offset, period, duration) for each of the scheduled actions in your application, and provides you with a graphical interface that can be used to modify these settings to avoid conflicts.

1. Open the Features window for the relevant Rhapsody® component, and select the Scheduling tab.
   The top part of the screen displays all elements that have been defined as periodic. Towards the end of the screen colored rectangles, representing each scheduled occurrence of the action. Beneath the listed periodic elements there is a catch-all row of rectangles that represent any timed actions that are not included in the scope of the component.
2. If you want, customize the appearance of the timeline by modifying the values for Time Scale, Scale Primary Step, and Scale Secondary Step. You can also toggle the display of vertical time lines using the Show Vertical Time Lines option.
   The Show Execution Log option refers to the ability to display execution log data together with the planned schedule (see Comparing designed schedule with actual execution).
3. If you want timing conflicts to be highlighted, verify that the Show Time Conflicts option is selected.
   Conflicts are displayed as small triangles. For each conflict found, one triangle is displayed at the appropriate location on the time line - the color of the triangle matches the color of the action that is causing the conflict. A second triangle is displayed directly before the action causing the conflict - here, the color of the triangle matches the color of the action that is already using that time slot.

   Note: When identifying conflicts between two actions, precedence is always given to the action that is scheduled at an earlier point along the timeline, meaning that the later action is always marked as the problematic one.
4. You can modify the timing information for each periodic element using either of the following approaches:
   • Modify the numbers displayed on the screen by clicking and editing.
   • Drag the rectangles as follows: dragging from the right edge extends or shortens the duration, dragging from the left edge extends or shortens the period, dragging from the middle of the rectangle increases or decreases the offset.
5. Click Apply to apply the changes to your model.
