The system will change scheduling so that the order is scheduled
without relationships, in other words, all the operations willbe considered as sequential and scheduled accordingly.

If you want the order to be scheduled in such a way that relationships
are taken into account, you must create relationships between theoperations.If all the operations are to start at the same time, for example, you
must link them all with an SS-relationship.
