The data loader is a step in the data collection process. After data has been collected from the managed systems, the data loader stores the aggregated data packages in the cubes. In the InfoCube or TwinCubes, data loading into the cubes can fail, for example if the RFC connection between SAP Solution Manager and the remote BW does not work, a data package contains an invalid character, or the data packages contain other errors and cannot be written into the cubes.

In case of an error during the loading of data into the InfoCube, the framework tries to load it again and again. You cannot see that an error occurred. If such error situations occur for the TwinCube, the data loader puts these data packages into quarantine (error queue). The data loader status turns red.

You can view packages that could not be loaded into the TwinCubes, by choosing the Display Error Queue button. After an issue was solved, you can release data packages so that they will be loaded into the TwinCubes again.
