I. Downloading and Installing Pentaho Report Designer

1. To download Pentaho Report Designer Tool please click on the following link,

https://sourceforge.net/projects/jfreereport/files/latest/download

Note: The current version of Pentaho Report Designer is 5.0.1

2. It will be the zipped file with size around 268 MB.

3. Download it and unzip it in the required directory.

4. Copy mysql connector jdbc into lib folder. http://dev.mysql.com/downloads/file.php?id=457911

II. Starting Pentaho Report Designer

1. Go into the unzipped 'Pentaho Report Designer' folder and double click on 'report-designer.bat' file(for Windows).

2. Once Pentaho Report Designer tool starts, you will be welcomed with the following window.

III. Creating Your First Pentaho Report

1. Go to the 'File' Menu and click on 'New' button.

2. Go to the 'Data' tab, click on 'Add Data Source' and then click on JDBC.

3. Once you click on JDBC, the following window will open, where you need to click on '+' (Create New Connection) button.

4. Once you click on 'Create New Connection', the following window will appear. Here, you have to provide all the setting information as given in the following table and then click on 'Test' button to generate the Message Box where it shows the confirmation of connection. Once Connection is established click on 'OK' button.

SI.NO	Field Name	Description
1	Connection Name	Provide the appropriate connection name
2	Host Name	This is the name of server to which designer tool connects to. In this case, we are connecting to 'localhost'.
3	Database Name	Provide the database name to which designer tool needs to connect. In MifosX, we generally connect to the database 'mifostenant-default'
4	Connection Type	In the left column, please select the appropriate connection type(in this case, mysql) . Once you select 'mysql' the Port Number automatically selected as 3306.
5	User Name	Provide the mysql username( in this case it is 'root')
6	Password	Provide the mysql password.

5. As shown in the following window, click on '+' button to add the sql query.

6. Here, Provide the Sql Query Name and write the appropriate Sql Query and then click on the 'Preview' button to confirm that, the Sql query executed successfully. Then click on the 'OK' button.

Query example

select mc.firstname,mc.lastname,mc.account_no from m_client mc where mc.activation_date between ${startdate} and ${enddate}

7. Once you create executable Sql Query, you may have to add parameters if required. In order to embed Pentaho Report to MifosX, At least you have to create 3 parameters which are passed to MifosX, namely:

• tenantUrl

• username

• password.

To add parameters, under the 'Data' tab, scroll down to see 'parameters' and then right click on 'parameters' and then click on 'Add parameter' to see the following window.

SI.NO	Parameter Name	Parameter Fields
1	tenantUrl	Name:tenantUrl Label:Tenant Db Value type: String Default Value: jdbc:mysql://localhost:3306/mifostenant-default Check mandatory
2	username	Name:username Label:User Name Value Type: String Default Value: root
3	password	Name:password Label:Password Value Type: String Default Value: mysql Check Mandatory Field
4	startdate (For this example)	Name:startdate Label:Start date Value Type: Date (SQL) Display Type: Date Picker
5	enddate (For this example)	Name:enddate Label:End date Value Type: Date (SQL) Display Type: Date Picker

Basically, these three parameters are required to embed Pentaho Report in MifosX. Similarly, you can define more parameters as per requirement of the report.

8. Once you add the parameters, you need to check whether the report is working fine in the pentaho environment. First, You need to add the Report fields into 'Details' section of the pentaho environment. In our example, the fields 'firstname', 'lastname' and 'account_no' of the clients are added. In order to add them you need to drag each field in 'Details' section of the pentaho environment as shown in following two screenshots.

9. Next you need to click on the 'Run' button and choose appropriate format for the report.

10. Once you 'Run' the report by choosing appropriate format, the following window will open where you enter the parameters and generate the report. (In this case, PDF is selected).

11. If you click on the 'OK' button and a PDF is generated, it means Pentaho Report was created successfully.

12. Add Global scripting once you are done with all the design and testing. Before you save the report you need to add global scripting.

Copy this content into it

// This is a template to demonstrate the existing functions
// you can use in a global data-source script. All functions and
// global variables you define here will be available for the
// all query scripts.
//
// Feel free to delete any function you don't use.
//
// you can process scripts via
// scriptHelper.eval("println ('Hello World');", "ECMAscript");
//
// or your can load your own ECMA/JavaScript files and execute them via
// scriptHelper.evalFile ("/your/file/here.js", "ECMAscript");
//
// both inline scripts and files will be executed in the global context -
// any function or variable defined there will be available globally.
//
// The following global variables exist by default:
// resourceManager : The ResourceManager can be used to load files
// contextKey : ResourceKey the context key points to the prpt-bundle
// dataFactory : The current datafactory instance
// configuration : The current report configuration
// resourceBundleFactory : Access to translations and locale information

function init(dataRow)
{
// place all initialization logic here. This is the right space to
// prepare complex lookup tables or to fill global variables.

// this method is called once when the data-source is first used.
var tenantUrl = dataRow.get("tenantUrl");
var user = dataRow.get("username");
var password = dataRow.get("password");
dataFactory.getConnectionProvider().setProperty("user", user);
dataFactory.getConnectionProvider().setProperty("password", password);
dataFactory.getConnectionProvider().setUrl(tenantUrl);
}

function shutdown()
{
// place all shutdown logic here. If you use any persistent resources
// like files or connections make sure you close them here.

// this method is called once during the data-source shut-down. It
// will be called after all query scripts have been shut down.

}

13. You need to save the report with '.prpt' extension. In order to do it, Just go to the 'File' menu and click on 'Save' button.

IV. Embedding Pentaho Report in MifosX

1. Create a '.mifosx' folder (use DOS to create the folder) in your home directory and then create a sub folder 'pentahoReports' in '.mifosx' folder.

2. Please copy the pentaho report file( with *.prpt file extension) which you have created earlier using 'Penntaho Report Designer Tool' in "home/.mifosx/pentahoReports" folder.

3. Go to Community-app and then go to Admin >> System >> Manage Reports and click '+Create Report' to see the following window.

4. Ensure 'Report Name' should be the same as the pentaho report file name (that is in this example, "Activated Clients.prpt").

5. Select Report Type as 'Pentaho' from drop-down list.

6. Ensure to check the box for "Use report(UI)".

7. Select the required parameters which are passed to pentaho. (in this case, startDate, endDate).

8. Click on the 'Submit' button to create the report.

V. Generating created Pentaho Report

Go to Community-app and then go to 'Reports' tab and then by selecting the report section>>then the required report you could generate the report.

In this example: Reports>>clients>>Activated clients.
