Drill in Business Objects(BO)
With Business Objects(BO) the data
is analyzed in different perspectives. BO data can be organized using different
mechanisms like DRILLING or SLICING and DICING.
On report analysis:
Allows to work directly on the data
in the report using drag and drop or with simple mouse clicks.
The data can be added from the
Report Manager to create tables and sections.
Option to replace, swap and re‐organize
data on the report is possible.
Sort, filter, and rank is possible
using a simple mouse click to focus the analysis on a slice of data.
Drill mode:
Allows to analyze data from
different angles and on different levels of detail. Typically, start off by
looking at the high level data and when you spot an unusually low or high
value, or an unexpected value, you can analyze it by displaying related data on
a more detailed level.
Slice and Dice mode:
Allows to organize data for analysis
in the slice and dice panel. Slice and dice panel allows to add, delete, and
swap data round, to analyze the data from a different viewpoint.
DRILL MODE :
Drill mode is an analysis mode that allows breaking down of data and view on different angles and different levels of detail to discover what the driving factor is behind a good or bad result.

Objects in a universe are organized
in hierarchies, with the most general object in the class at the top and the
most detailed at the bottom. Objects are organized in this way for drilling.
When the data is analyzed in drill
mode, the hierarchies are used. The universe classes are the default
hierarchies used for drilling but the universe designer can also set up custom
hierarchies.
Creating hierarchies is possible at
report level too.
Drill hierarchies contain dimension
objects only. Drill is possible on dimension objects, not on measures or
details.
Scope of Analysis
Before analyzing data in drill mode,
set up the scope of analysis. “Scope of analysis” means a subset of data,
returned by a query, that will be used for analysis in the report.
Drilling Options
The table, crosstab, or chart that
needs to be analyzed in drill mode is selected first. The different options
available in drill mode are:
Drill-Down : The next level of detail in a
hierarchy is viewed. During drill down, you view data at more detailed levels.
Drill-Up : During drill up, you go back up
through the hierarchy to display data on less detailed levels.
Drill-By : When you drill down and up you move
through the levels of the same hierarchy. However, if you cannot find the
answer to a question by analyzing data in its current hierarchy, you can move
to another hierarchy to analyze other data.
Drill-Through : If the lowest level of detail
required is not currently available in the report, you can drill through to the
database directly from drill mode and get the required data. You do not
have to edit the query in the Query Panel.
Drilling on Multiple Hierarchies
If a block contains more than one
hierarchy, you can simultaneously drill down from one dimension to the next in
all the hierarchies in the block.
For example, Double‐click on the
Revenue column in the cell that displays revenue for Hawaiian Club in FY1998.
Desktop Intelligence moves Resort
and Year to the Drill toolbar. The values in the Drill toolbar are Hawaiian
Club and FY1998. Service Line and Quarter appear in the table and Desktop
Intelligence updates the Revenue column.
Drilling Using Custom Hierarchies
You may find that the default order
in which dimension objects are arranged in hierarchies is not optimal for your
analysis needs, or that you need to drill on a hierarchy that has objects from
different classes.
You can edit a hierarchy by changing
the order of the dimensions it contains, by adding dimensions to it, and
removing dimensions from it. You can also rename a hierarchy, and even delete
it.
You can also create your own
hierarchies using dimensions available in the report or by using user objects.
There are two types of custom hierarchies:
Pre‐defined custom hierarchies that
are set up by the universe designer and which can be re‐used in other
documents.
Hierarchies you create yourself and
which are saved only in the document you created them in
