You use this function to define the offset between the start or end of a secondary resource and the dates of the superior phases or the superior operation.

When scheduling master recipes and process orders, the system uses this data to determine secondary resource dates.

You define the earliest and latest dates of a secondary resource by entering the following data:

• An offset between the start date of the operation or phase and the start date of the secondary resource
• An offset between the finish date of the operation or phase and the finish date of the secondary resource

The secondary resource dates can both be before or after the corresponding reference date. If the dates are before the reference date, you enter the offset as a negative value (that is, followed by a minus sign).

If you do not enter any offsets for a secondary resource, the system uses the relevant reference date as the secondary resource date.

You define offsets in the detail data for the secondary resource on the Standard values tab page. You can access the detail data from the secondary resource overview by double-clicking the corresponding secondary resource.
