How To Fix DT315 - Clave externa texto de tabla & ya definida:

SAP Error Message - Details

• Message type: E = Error

• Message class: DT - Table activation (incl. indexes)

• Message number: 315

• Message text: Clave externa texto de tabla & ya definida:

¿Qué causa este problema?

There is usually only one text table for a check table.
In this case, a text foreign key which already has more foreign keys
was defined for a check table.
The text tables which already exist are listed in the next log lines.

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 whether this table or the listed text tables are really a text
table for the check table.
If several text tables were defined, this can result in problems if
text for a table is automatically read.
This is true for example for the possible values function and when
generating maintenance views.
