¿Qué causa este problema?

This activity type has already been marked for creation, but can only
be created via a BAPI callup for a single time interval, and may not
already exist on the database.

Respuesta del sistema

The system deactivates the current entry in the list of activity types
to be added. Only the initial entry for the activity type is retained
as active.

¿Cómo arreglar este error?

If you want to create additional time intervals for the activity type,
you should use the standard transactions for activity types.
