Adding Constraints to the Manufacturing Gantt Explorer
The Manufacturing Gantt Explorer can be used to test various constraint scenarios. For example, to see what effect applying a constraint to an operation has on other operations, or on resource load levels.
* 
Constraints that are applied in the Manufacturing Gantt Explorer are only displayed in the Manufacturing Gantt Explorer, and are not saved back to the Windchill MPMLink database.
To add a constraint using the Manufacturing Gantt Explorer:
1. In the Manufacturing Gantt Explorer click the add constraint icon .
2. In the task bar of the operation for which you would like to apply a constraint, position and click your cursor at the location in the task bar where the constraint is to begin.
3. Drag your cursor to the position in the task bar of the second operation.
