Constraints

 

A constraint is a warning function applicable to the creation or modification of one or more events.

Constraints can be visualized in the form of an error message or indicator.

Those activated are applicable when events are created, moved or modified, to verify that there is no contradiction with other pre-existing events.

Constraints may have an imperative effect (preventing creation or modification), or may just simply trigger a warning message.

There are three types of constraint:

  • Target constraints,
  • Coherency constraints,
  • Time gap constraints.

It is possible to create as many constraints as possible.

Nevertheless, for application performance reasons, it is recommended that a limited number are activated.

Note

It is possible to add an external constraint through a specific development. This possibility will be analyzed by the STILOG Development department.
