Changing Relationships

Before making any changes to relationships, you should consider whether the changes are really necessary, since they may affect the scheduling of the whole order.
Deleting Relationships

If you delete the relationships in an order, the operations affected are removed from the network structure. If you then schedule the order, the system assumes that these operations start at the same time, independent of one another.
If you delete a relationship, you change the network structure. Before you delete relationships, you should therefore make sure that execution of the order has not yet begun.

Once all the relationships have been deleted, the system automatically adjusts the scheduling for the order. The system informs you of the change in an online message.
