What causes this issue?

You want to adjust the duration of a network activity to the maximum
delivery time or replenishment lead time of all allocated material
components.

System Response

The system only calculates using the allocated material components that
have the indicator <ZH>Alignment finish date</> set. The maximum
duration comes from
the planned delivery time when the material components are procured
externally
the total replenishment lead time when the material components are
produced internally or the in-house production time if the total
replenishment lead time is not maintained in the material master

How to fix this error?

Make sure that the <ZH>Alignment finish date</> indicator on the
component detail screen of the activity is set for all material
components allocated to the activity.
