This set of slides is part of the course Data Visualization GE, available on FIWARE platform, whose SpagoBI is the reference implementation. Here it is shown how to set filters to a parametric Birt Report on SpagoBI Server.

2. Birt Report Designer
TOPIC OF THE COURSE: In
this course we will see
how to assign parameters
to any analytical
document, such as Report
with Birt, Qbe, Olap, etc.
Parametric Report

3. To accomplish the task one needs to build up:
●
the LOV which stands for List Of Values. It means to develop the
set of values that the parameter can assume;
●
the Analytical driver which manages the connection between the
end-user, the document and the LOV.
In the following there will be more explanations about these two
concepts.

4. SpagoBI allows you to define a LOV in
multiple ways …
➢
Statically
➢
Querying a database
➢
Using a script
➢
Calling an external object
Each record in a LOV can be composed
of multiple attributes (ex. Customers):
[A.Catherine, 4559 Julpum Loop,
Beaverton,USA], [A.Joyce, 3761
Cancroft, San Gabriel,USA]). One of
these attributes represents the actual
value. The others are just descriptive.

5. Click on the Profiling button
and select Lovs Management
from the contextual menu.

6. Start a new Lov using the button at the right corner of the
page.

7. Fill in the mandatory fields (marked with the *) and choose in which way
you want to implement the LOV. As an example we will choose the “Query
statement” one.

8. Insert the query in the Query definition box and test it using the specific
comand

9. When the LOV works fine you have to define some meta-information
Select the column that
must be shown to the
user
Select the value to be
sent to the report

10. Then finally save it and go on with the next step: create a new Analytical
Driver.

11. An analytical driver is an autonomous entity that models a business
concept in order to use it as a discriminating criterion in the global data
context, according to the different end-users’ roles.
It works as a variable that can take its runtime value from different
LOVs. The actually used LOV and, therefore, the actual range of
possible values, depend on the role of the user that uses the analytical
driver itself.
Designing an Analytical Driver means answering the following
questions:

12. Start a new Analytical Driver using the button at the right
corner of the page

13. You'll be asked to fill in the mandantory fields marked with *. Observe
that you can choose for the Type between Date, String or Number.
SpagoBI display
Date Widget.
SpagoBI send
data as Integer
to the Report
SpagoBI send data as
String to the Report
REMEMBER TO
SAVE and keep on
filling in

14. You'll be asked to fill in the mandantory fields marked with *. Observe
that you can choose for the Type between Date, String or Number.
REMEMBER TO SAVE
and keep on filling in
➔ Select Functional if analysis data will be drived by the current AD
➔ Select Temporal if this AD depends on the time and it can be
conveniently computed by the Scheduler by means of a formula

15. IT'S IMPORTANT TO
➢ Fill in the
mandatory fields.
➢ Associate the
corresponding
LOV to the AD .
➢ Attribute Roles to
the AD.

16. We stress that one can add distinct operational
methods to an AD and relate them to different
roles. This way the same AD displays different
values with a certain data visualization
accordingly to the end-users' roles.

17. Relate Analytical Driver and
document

18. Edit the document (using document detail )
At the bottom of
the page select
New from the
dedicated section
Document
Analytical Driver
Detail.

19. ➢
Fill in the mandatory fields and
add the AD clicking on the icon at
the end of the row.
➢
Insert in the Url Name box the
exact name of the parameter
used in your
report/qbe/olap/whatever….
USE THE GREEN TICK
TO SELECT THE
AD

20.  To sum up:
 Edit the document ( using document detail )
 Select New and fill in the mandatory boxes
 Add Driver at the bottom of the form.
 REMEBER TO SAVE AS SOON AS YOU THINK YOU'RE DONE WITH
THE INSERTION
Remember the URL NAME value
must be identical to the report
parameter name

21. Repeat the procedure and assign as many parameters as the
report is configured

22. Open your document and check parameters. Click on the Execute
button to run your statistic.

23. Thanks!Thanks!
