¿Qué causa este problema?

An activation lock is always set when you start an activation for a
single ABAP/4 Dictionary object or with the mass activating program.
This lock prevents objects of different object classes from being
activated in parallel, which could result in inconsistencies in the
ABAP/4 Dictionary. The lock is automatically cancelled when the
activation has ended. If an activation terminates, the lock first
remains in effect. It cancels itself after about 10 minutes.

Respuesta del sistema

The activation task is rejected.

¿Cómo arreglar este error?

Repeat the activation after a few minutes.
