You can maintain overlaps between orders in a collective order. During scheduling, the system creates overlaps between the last operation in the subordinate order and the operation in the superior order in which the components are required, according to the settings you have made. Only the minimum move time of the last operation in the subordinate operation is used in scheduling.

For an order in a collective to overlap with a superior order, the following requirements must be fulfilled:
An offset (Offset field) is the time between the requirements date of the component and the basic finish date of the subordinate order. You maintain this in Component detail data on the General data tab page in the Relationship menu.
