Local cubes and local mining models allow analysis on a client
workstation while it is disconnected from the network. For example, a
client application might call the OLE DB for OLAP 9.0 Provider
(MSOLAP.3), which loads the local cube engine to create and query local
cubes, as shown in the following illustration:
Create the XMLA script using server cube. Then copy script
to Clipboard.
Specify the local cube path and the filename (including .cub as the extention) as the server name. Then press "connect" which will create cube file.
Open a new XMLA query window by right clicking on local cube
connection and paste the script copied above.
You can search for following elements in the script file to make
sure that you are connecting to right database.
<ConnectionString>
Right click on the local cube database and click “Process”
Ignore following error messages
Value cannot be null.

.cub file can be simply browsed using Excel (2010/2013) and
you will get the same interface that you get when access SSAS server cube using
Excel.
.cub file can be also simple connected to XLCubed by creating
XLCubed connection. Connection type should be “Analysis Service Cube File.
- Local cube files can dramatically improve
browsing speed performance, especially when analysing low levels of large
dimensions.
- Local cube files can also improve browsing
performance because requests for additional data are handled on the local
computer rather than across a network on an Analysis Server.
- Local cube files can now be encrypted and
password-protected.
- Analysis Services 2005 provides more precise
control over the creation of local cube files.
- When you use local cube files you can give each
user the specific data they need, or want, or are allowed to see.
- When creating local cubes from server-based cubes, the
following considerations apply:
- Distinct count measures are not supported.
- When you add a measure, you must also include at
least one dimension that is related to the measure being added.
- When you add a parent-child hierarchy, levels
and filters on a parent-child hierarchy are ignored and the entire parent-child
hierarchy is included.
- Member properties are not created.
- When you include a semi-additive measure, no
slices are permitted on either the Account or the Time dimension.
- Reference dimensions are always materialized.
- When you include a many-to-many dimension, the
following rules apply:
- You
cannot slice the many-to-many dimension.
- You
must add a measure from the intermediary measure group.
- You
cannot slice any of the dimensions common to the two measure groups involved in
the many-to-may relationship.
- Only those calculated members, named sets, and
assignments that rely upon measures and dimensions added to the local cube will
appear in the local cube. Invalid calculated members, named sets, and
assignments will be automatically excluded.
