¿Qué causa este problema?

You want to calculate the time interval of the relationship as a
percentage of the duration of the predecessor. But no work center has
been entered for this activity and therefore no calendar is available
to perform this calculation.

Respuesta del sistema

The function is carried out. If you have not entered a work center for
the predecessor, the system uses the factory calendar to calculate the
time interval that you have maintained in the network header or the
header of the standard network.
