Coherency constraint


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

The Coherency constraint may be in one of three forms:

  • The creation or modification of an event is prohibited;
  • Warnings, via a message, that the actions undertaken do not remain within the constraint;
  • Authentication, via a message, that the user has re-entered their password.

The Coherency constraint is applied using three filters:

  • The selected dimension filter;
  • The events filter for triggering the constraint;
  • The events filter to verify the constraint.


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