¿Qué causa este problema?

This usually happens if several parallel-running jobs are creating
conversion objects simulaneously. It might happen that two objects refer
to the same DDIC structures of the sender or receiver system (for
example, two tables use the same includes). In order to prevent
potential problems with the DDIC activation of shadow structures in the
central system, a logical lock must be acquired by the job that
processes the objects. If this lock can't be obtained in a due time
interval, the processing of the corresponding conversion object is
stopped. The object is set to "error" state and the system proceeds with
the processing of the next object.

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?

Repeat the creation of the conversion objects. Usually the problem
disappears if the processing is repeated.
