How To Fix AD999 - Fonction "activer" actuellement bloquée (F1)

SAP Error Message - Details

• Message type: E = Error

• Message class: AD - Data Dictionary application messages

• Message number: 999

• Message text: Fonction "activer" actuellement bloquée (F1)

Quelle est la cause de ce problème?

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.

Réponse du système

The activation task is rejected.

Comment corriger cette erreur?

Repeat the activation after a few minutes.
