SAP Error Message - Details

• Message type: E = Error

• Message class: USMD1A - Messages: Abstraction Layer

• Message number: 051

• Message text: Tipo entidad &1: Imposible considerar restricción a &2

¿Qué causa este problema?

You want data of entity type &V1& to be read. But you have limited your
selection to entity type &V2&, which acts as an additional key in a
dependent entity type.
The system could only consider this restriction if at least one of the
following conditions were fulfilled:
There is only one dependent entity type in which the entity type &V2&
acts as an additional key.
The entity types, in which entity type &V2& acts as an additional key,
are all dependent on exactly one other entity type in which entity type
&V2& also acts as an additional key.
An attribute of one of the dependent entity types, in which entity type
&V2& acts as an additional key, is also limited further.
For the current search query, none of these conditions are met.

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?

Restrict further to an attribute of one of the dependent entity types,
in which entity type &V2& acts as an additional key.
