Constraining Activities

A constraint is a way to restrict the range that an object may move in time. If an object has been constrained, any attempt to move it beyond its constraint date will be prevented. Constraints are represented by exclamation marks to the left or the right of the date they’re constraining.

NetPoint supports two types of constraints: a no-earlier-than (NET) constraint, also called a start-no-earlier than (SNE) constraint, which defines the earliest date an object may backslide in time; and a no-later-than (NLT) constraint, also called a finish-no-later than (FNL) constraint, which defines the latest date an object may slide forward in time. In the case of activities, no-earlier-than constraints are applied to start dates and no-later-than constraints are applied to finish dates. To set constraints for more than one activity or milestone at the same time, see Bulk-Editing Objects.

NOTE: Once set for the first time, if the constraint is subsequently turned off, NetPoint continues to remember the date for future use.

Steps

  1. With the Select Tool Select Tool Icon chosen in the toolbar, double-click the desired activity, or right-click it and choose Properties. The Activity Object window will open.
  2. Click the Dates tab.
  3. To apply a NET constraint, check the box next to Start no earlier than. The constraint will default to the current start date.
  4. To apply a NLT constraint, check the box next to Finish no later than. The constraint will default to the current finish date.
  5. To change the constraint date, enter a new value or click the down arrow button. Selecting a date on the calendar closes the graphic calendar picker.
  6. When finished, click OK to exit the window and apply the constraint. An exclamation mark will show up where the constraint was applied.
