¿Qué causa este problema?

A project object is to be created or changed, and classified at the
same time. The project object is assigned to class <ZH>SAP_KKR_CLASS</>
(class type 014).
However, the entire class is currently locked.

Respuesta del sistema

The project object cannot be created or changed while the transaction
that caused the lock is still running.

¿Cómo arreglar este error?

Wait until the transaction is finished. Transactions that lock the
class for extended periods of time should not be run during normal
online operation.
You can find out who is locking the class with transaction SM12:
Search for locks for table KSSKX. In the subsequent list, search for
lock argument <ZH>014SAP_KKR_CLASS</>.
