When you create tasks, the tasks maintain the start date that you specify. In addition, TRIRIGA provides a "minimal" Gantt Strict mode. This setting is system-wide, so it must be consistent across all servers.

When you create tasks, the tasks maintain the start date that you specify. The next tasks are moved left only to correct dependencies, and do not need to be close to their ancestors. Your application administrator can enable Gantt Strict mode by setting GANTT_STRICT_MODE=TRUE in the TRIRIGAWEB.properties file on the TRIRIGA server. All next tasks are moved left or right to be as close as possible to their ancestors and to not violate any dependencies or constraints.īy default, the as-shipped TRIRIGA applications do not use Gantt Strict mode. First tasks are tasks that do not have incoming dependencies or constraints specified. With Gantt Strict mode, all first tasks are required to start directly on the project Plan Start date or end directly on the project Plan End date depending on the value that you select for the project Calculate Project From field. If your application administrator has enabled Gantt Strict mode, the project Plan Start date determines the placement of your tasks.

The Gantt scheduler handles "As Soon as Possible" constraints on your tasks in two different ways, whether Gantt Strict mode is enabled or disabled. The default Constraint Type for new tasks is "As Soon As Possible". The fields in the Summary section can be changed as required except for Plan Start. All other fields must also contain the previously saved values. If you do not add a Plan Start date for the project, it defaults to the date that you created the project. The Date field auto populates with the date that you create the project. Depending on the project form, the Schedule tab or the Tasks tab contains several more required fields, Time Zone and Calculate Project From. On the General tab, the Date, Name, and Currency are required. When you create a project, the Plan Start date is required but the Plan End date is not required.
