The SAP error message RSO_RES_QMSGS134, which states "All targets are now decoupled from &1," typically occurs in the context of SAP BW (Business Warehouse) when dealing with data targets such as InfoProviders, DataStore Objects (DSOs), or InfoCubes. This message indicates that the data targets that were previously linked to a particular source (like an InfoSource or a DataSource) have been decoupled or disconnected.
Cause: Decoupling Action: The most common cause of this error is that a decoupling action has been performed intentionally or unintentionally. This could happen during a data model change, where the relationships between data sources and targets are modified. DataSource Deactivation: If the DataSource or InfoSource has been deactivated or deleted, all targets associated with it will also be decoupled. Transport Issues: If changes were transported from one system to another (e.g., from development to production), and the targets were not included in the transport, this could lead to decoupling.
