¿Qué causa este problema?

In a help view, you specified a selection condition for a field of a
secondary table.

Respuesta del sistema

The base tables of help views are linked with an "outer join".
This means that the entries of the primary table are displayed even if
there is no corresponding record in the secondary tables. Selection
conditions for the secondary table should be understoood in this
context. They do not cause records to be selected from the primary
table.
Selection conditions for secondary tables make sense if there is more
than one record of a secondary table for a record of the primary table
and the selection condition would ensure uniqueness.

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 if the above-described behavior corresponds to what you wanted to
achieve with the selection condition.
