Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    MB: IMetabase;
    Desc: IMetabaseObjectDescriptor;
    Eax: IEaxAnalyzer;
Begin
    MB := MetabaseClass.Active;
    Desc := MB.ItemById("DB");
    Eax := MB.ItemById("Eax").Edit As IEaxAnalyzer;
    Eax.ClearDataSourceCache;
    Debug.WriteLine("Created: " + Eax.CreateDataSourceCache(Desc).ToString);
    Eax.RefreshDataSourceCache;
    Debug.WriteLine("If there is cache object: " + Eax.IsDataSourceCacheExist.ToString);
    Debug.WriteLine("Source cube name: " + Eax.DataSourceCache.Parent.Name);
End Sub Button1OnClick;

After executing the example a cache object is created for the express report source in the database with the DB identifier. The console window displays result of creating a cache object, result of checking if the cache object exists, and name of source cube.
