To change a constraint, first you must enter the dependency net to which the constraint is allocated. You can make changes that are valid immediately or changes that become valid on a specific date in the future. If you want to make your change in the future, you must enter a change number with the valid-from date you require (refer to Changing a Single Dependency).

1. Choose Dependency ® Dependency net ® Change.
2. If you want your change to become valid on a specific date in the future, enter a valid change number.
3. Choose Goto ® Allocations.

You can change the allocations to the dependency net.

4. If you want to make changes to a specific constraint, select the constraint you require.

If you choose Environment ® Change overview, you can display the validity period of a constraint.
