¿Qué causa este problema?

Certain time limits apply to the activation of ABAP/4 Dictionary objects
in SAP in-house systems. You can flag objects for batch activation by
entering them in table TACOB using transaction SM31. You need to enter
the type and name of the objects concerned.
In this instance the object has already been entered for batch
activation.

Respuesta del sistema

El sistema emite un mensaje de error y no le permitirá continuar con esta transacción hasta que se resuelva el error.

¿Cómo arreglar este error?

Check the entry in table TACOB and the associated log. If an error
message is entered in table TACOB for an error in the object that has
already been eliminated, remove the error message from table TACOB in
order that the object is processed in the next batch activation.
Otherwise you need to start by eliminating the error.
