Offline OLAP – Working with Disconnected Analysis Service Cube

Microsoft introduced a cool feature in Excel 2007 called Offline OLAP that enables you to work with an Analysis Services Cube in disconnected mode. The Offline OLAP feature basically snapshots a version of the cube into a local cube file which can be used by Pivot Tables.

Some potential scenarios where the offline cube file can be really helpful:

  • Proof of concept demos to client can be done using the local cube file without having to worry about the network bandwidth, access and unfamiliar environments.
  • Accessing your reports while commuting or in places where internet facility is not available.
  • Snapshoting the stable version of cube during development phase especially when certain development activities can potentially bring down the cube.

Creating Offline Cube File

To create the Offline Cube file, click on you Pivot Table and navigate to PivotTableTool>>Options>>OLAP Tools>>Offline OLAP (shown in Figure 1)

A wizard pops up. Click Create Offline Data File button (shown in Figure 2).

The subsequent wizard steps allow you to select the dimension attributes, members, hierarchies, measures and calculated measures. By default the cube members used in the PivotTable is selected. (Figures 3 and 4) .

The final step is to save the data to a local cube file (figure 5)

Switching to Online mode

To switch from offline to online mode, navigate as before PivotTableTool>>Options>>OLAP Tools>>Offline OLAP and select the On-line OLAP option which is now enabled (figure 6).

Editing Offline Cube File

To edit the offline cube file, navigate to PivotTableTool>>Options>>OLAP Tools>>Offline OLAP and select Edit offline data file option.

Offline OLAP is a really cool feature in certain scenarios. One improvement that I would prefer to see is some kind of visual differentiation to indicate that the PivotTable is in offline mode which is currently not available.

    hi Benny
    Your article was a good read.
    I had used “CREATE GLOBAL CUBE” command few days ago and was impressed by its simple syntax. It also produces a .cub file on the server and possibly quite useful for automation of producing multiple .cub files restricted by security requirements of dimensions / measures / etc.. although, I haven’t used it that way but just some random thoughts.

    cheers

    Are there any limitations when using an offline cube versus using an online cube?

      Masson, I am not aware of any difference in cube browsing between online and offline browsing modes.
