What is needed to make a database table client dependent in the ABAP Dictionary?

To make a database table client-dependent in the ABAP Dictionary, the requirement is to include a key field of type CLNT. This key field acts as the client identifier, which allows the system to manage multiple client data within the same table. Each client can have its own set of records without any overlap with other clients, enabling the multitenancy feature of an SAP system.

The presence of a key field with the type CLNT is crucial because it defines which client the specific records belong to, ensuring proper data segregation and security. This structure reflects SAP's multi-client architecture, where each client operates independently yet shares the same system resources.

The other options, while related to table properties and definitions, do not establish client dependency the way a designated CLNT key field does. For example, technical settings may govern other aspects of the table's operation, but they do not enforce client dependency on their own. Similarly, annotations or the absence of special settings might be relevant elsewhere within the context of database definitions, but they do not fulfill the key requirement for establishing client dependency in this specific manner.
