INTRODUCTION

The report-publishing framework in Oracle E-Business Suite (EBS) R12 has undergone a
major change, and consultants are facing some challenges in applying the new technology
stack. In this white paper I will address some issues that could be faced when implementing
Oracle BI (XML) Publisher as a report publishing solution, and some suggested solutions and
best practice guide in the implementation.

I will look at the following major areas within the whitepaper

1. How Oracle BI (XML) Publisher Report works
2. How Oracle BI (XML) Publisher reports are developed
3. Key environment setup steps
4. Solutions to possible development issues

This is not a definitive guide, but it will assist the average implementer to successfully
implement a solid Oracle BI (XML) Publisher solution within Oracle EBS R12.


WHAT IS ORACLE BI (XML) PUBLISHER?

Oracle BI (XML) Publisher is a template-based publishing solution embedded in Oracle E-
Business Suite. It provides a new approach to report design and publishing by using desktop
tools with XML technology.

“Oracle Business Intelligence Publisher (BI Publisher, formerly XML Publisher) is an
enterprise reporting solution to author, manage, and deliver all types of highly
formatted documents eliminating the need for costly point solutions. Built on open
standards, IT staff and developers can create data models against practically any
data source and use BI Publisher APIs to build custom applications leveraging
existing data sources and infrastructure. End users can easily design report layouts
using familiar desktop tools, dramatically reducing the time and cost needed to
develop and maintain reports. Extremely efficient and highly scalable, BI Publisher
can generate tens of thousands of documents per hour with minimal impact to
transactional systems. Reports can be viewed online or scheduled for delivery to a
wide range of destinations.”

- Source Oracle Corporation
(http://www.oracle.com/technology/products/xml-publisher/index.html)

BI Publisher or XML Publisher?

The Oracle BI Publisher was formerly called XML Publisher, and it is now part of Oracle’s
Business Intelligence Suite. However the name XML Publisher is still used within the E-
Business Suite (EBS), PeopleSoft Enterprise and JD Edwards E1. Oracle BI Publisher is also
available as a standalone product. This white paper looks at the implementation within EBS
R12, and will refer to “Oracle BI Publisher” as “XML Publisher” as implemented in EBS R12.


WHY USE XML PUBLISHER

XML Publisher provides an opportunity for rapid report publishing, development and
maintenance. It is also possible to have multiple layouts in different languages for the same
data structure. Report output can be generated as Excel, Word, PDF and HTML at runtime.

The report layout can be developed in Rich Text Format (rtf), Portable Definition Format (pdf)
or eText format. The development of the report can be separated between the structure of
the data and the presentation of the layout.

The issue with traditional standard Oracle reports

Traditional Report Definition Files (rdf) are very difficult to maintain and have a high
development and customisation cost. The data logic, layout and translation are all in one file.
The output of the file is also displayed in a format that is not dynamic enough to be used for
further analysis in tools like spreadsheets.

Some Issues

Let us have a look at an assumed requirement to create an invoice in three languages in two
separate layouts. Such as, one layout for detailed invoice and another layout for summary
invoice with the same data. This requirement will require six different rdf files to be
developed. A small change in the layout would require amending all the six rdf files.

With XML Publisher, the same report would have required two rtf layout files and two XML
language translation files (XML Localization Interchange File Format - XLIFF). The change will
require slight changes to the layout files.


Another traditional issue is the layout presented by rdf outputs. In the diagram below, the
end user desires to display the extracted file as an Excel output. Due to the fixed format of
rdf, the report is not user-friendly for the requirements of the user.

The XML Publisher solution

XML Publisher allows the development separation of data, layout and translation. This makes
it flexible to develop and easy to maintain. The design of the report can be delegated to
consultants who are familiar with the desktop tools for layout customisation such as Adobe
Acrobat and MS Word. The solution can also be developed rapidly. The output of the report
can be decided at runtime.

In this whitepaper, we will look at the steps required to create an XML Publisher solution that
will create and extract to Excel as displayed below.


WHEN TO USE XML PUBLISHER

XML Publisher is suited mainly for the following types of reports output:

 Financial and business reports
 Invoices, purchase orders, receipts, Sales Orders, Statements
 Legal documents – Tax forms, Payslips, Cheques
 Newsletters, Marketing documents


HOW XML PUBLISHER REPORTS WORKS

The Process

1. Run the concurrent program
2. Concurrent program calls the data template in the Data definitions via the XDO
engine
3. The Data template calls the SQL Query in the XML file
4. The Database engine generates the output and converts it to XML format via the XML
Engine
5. The XML Output is generated
6. The Output is formatted using the Output Post Processor (OPP) based on the
definitions in the template definitions
7. The user views the output


The Output Post Processor (OPP)

Concurrent processing uses the OPP to enforce post-processing actions for publishing
concurrent requests with XML Publisher. After the concurrent manager finishes running the
concurrent program, it will contact the OPP to apply the XML Publisher template and create
the final output.

The OPP runs as a multi-threaded service, and will start a new thread for each concurrent
request it processes. If all the OPP services have reached their respective maximum number
of threads, the requests waiting to be processed remain in a queue to be processed as soon
as threads become available. If no threads are available the concurrent program may
complete with a warning.


HOW IT WAS DEVELOPED

Define Requirements

The Business Analyst and the Functional Consultant identifies the data requirements including
the layout of the data. The Functional Consultant produces a functional design document that
is passed on to the Technical Consultant for the technical design and development.

Create Data Template

The XML Publisher data template is the method by which the request for data is
communicated to the data engine. It is an XML document whose elements collectively define
how the data engine will process the template to generate the XML.


The Technical Consultant identifies where the data is held in the tables, and writes the SQL
query to fetch the data. The SQL query is used in the data template to extract the data.

Tip: To convert an existing Oracle Standard Report to an XML Publisher Report you do not
need to create a data template.

The data template is called using the Concurrent Manager.

Structure of the data template

Header – contains XML elements including: Doctype version, Data template tag and
Properties tag with property elements to support the XML output and Data Engine properties.

<?xml version="1.0" encoding="UTF-8" ?>

<dataTemplate name="GLXRLSEG" defaultPackage="GL_GLXRLSEG_XMLP_PKG"
version="1.0">

<properties>

<property name="xml_tag_case" value="upper" />

</properties>

The parameters used in the concurrent program and lexicals used for flexfields

<parameters>

<parameter name="P_SEGMENT_NAME" dataType =
"character"></parameter>

<parameter name="P_STRUCT_NUM" dataType = "number"></parameter>

<parameter name="P_CONC_REQUEST_ID" dataType = "number"
defaultValue="0"></parameter>

</parameters>


<lexicals>

</lexicals>

Data queries – The SQL statement

<dataQuery>

<sqlStatement name="Q_SEGMENT_LISTING">

<![CDATA[

select

v.flex_value segval,

vt.description segdesc,

…

]]>

</sqlStatement>

</dataQuery>

Triggers – before and after triggers can be defined if used

<dataTrigger name="beforeReportTrigger"
source="GL_GLXRLSEG_XMLP_PKG.beforereport"/>

The data structure is defined including any elements structure required.

<dataStructure>


<group name="G_SEGMENT_LISTING" dataType="varchar2"
source="Q_SEGMENT_LISTING">

<element name="segval" dataType="varchar2" value="SEGVAL"/>

<element name="segdesc" dataType="varchar2" value="SEGDESC"/>

…

<element name="atype" dataType="varchar2" value="ATYPE"/>

</group>

</dataStructure>

<dataTrigger name="afterReportTrigger" source="GL_GLXRLSEG_XMLP_PKG.afterreport()"/>

</dataTemplate>

More information on how to create the data template is found in XML Publisher -
Administration and Developer's Guide - http://download-
west.oracle.com/docs/cd/B40089_02/current/acrobat/120xdoig.pdf

Create the Concurrent program based on the data template

Responsibility: System Administrator

Navigation: Concurrent > Program > Define

Enter the following:

 The Concurrent Program name – use a naming convention for your custom programs
 Designate "XDODTEXE" as the executable for your concurrent program. This is the
XML Publisher Java concurrent program that will execute your data template.
 The Short Name that you assign to the program must match the Data Definition
Code that you assigned to the data template in the Template Manager. The XML


Publisher executable uses the short name of the program to locate the corresponding
data template in the Template Manager.
 You can optionally set the Executable Options for the Java heap size during
execution. This may be necessary for generating reports with large outputs. For
example –Xmx1024m sets it to 1GB.
 Select XML as the output format

Tip: to convert an existing Oracle
standard report to an XML Publisher
report, use the Copy to button to
create a copy of the existing report,
you need to change the Program
Name and the Short Name


More information on how to call the data template from a Concurrent Program can be found
in XML Publisher - Administration and Developer's Guide http://download-
west.oracle.com/docs/cd/B40089_02/current/acrobat/120xdoig.pdf

Enter Parameters

Click on the Parameters button to create the parameters. Enter the parameters details; note
that the Token should match the Parameter name in the data template.

Add the report to the Report’s request group

Assign the concurrent program to an appropriate Request Group for your users to run. When
your user submits the request, the Concurrent Manager executes the XML Publisher Data
Template Java concurrent program. The short name of the concurrent program is used to
locate the appropriate data template in the Template Manager.


Navigation: Security > Responsibility > Request


When the data generation is complete, the Concurrent Manager's Output Post Processor
applies the layout template to the generated XML.

Register the Report as a Data Definition in the Template Manager

Responsibility: XML Publisher Administrator

Function: Home > Data Definitions

Button: Create data definition

Enter the following information

 The name of your definition
 Enter the code - use the Concurrent Program short name as the code
 Select the application code - and use the same application code as defined in the
concurrent program.

Creating the data definition maps the data with the template layout. You can have many
layouts mapped to one data definition.


Click on the apply button to confirm the details

Attach the data template file to the Template Manager

You can add the following to complete your Data Definition:

 XML Schema is used for pdf templates
 Attach your data template XML file – required if your report data query is in the data
template xml file. Your report query may be in an Oracle Report (rdf) file or a PL/SQL
stored procedure
 Attach a sample XML output file if you want the user to preview the report before
they run it. This could be useful if you have defined multiple templates for the data
definition


Run the Report to extract the XML File

Menu: View > Requests

Save the output file as an xml file


Design Template

The Technical Consultant or Report Designer uses the XML file to design the rtf template.
Mark-up tags are added to the document to prepare it for merging with the XML data. XML
Publisher recognizes the formatting features and converts them to XSL-FO. The template is
designed in a word processing tool such as MS Word.

More information on how to create the layouts can be found in XML Publisher – Report
Designer’s Guide http://download-
west.oracle.com/docs/cd/B40089_02/current/acrobat/120xdorg.pdf


Register the template in the Template Manager


Function: Home > Templates

Button: Create Template

Assign the template to the Data Definition code of the report

Enter the following additional details

 The name of the report
 The application
 The code
 The template type
 The default output type
 Attach the template file
 Select the language
 Use the Translatable checkbox for XLIFF Files


Run the report

Menu: View > Requests

Select the options button to confirm the layout required


The output


ENVIRONMENT SETUP

The following set up is required for the XML Publisher solution in Oracle EBS R12

Profile Options

Set the following Concurrent Profile options


Navigation: Profile > System

Search for the Concurrent: %OPP%Timeout

Concurrent: OPP Process Timeout - This profile option specifies the amount of time the
OPP manager waits for the OPP to actually process the request.

Concurrent: OPP Response Timeout - This profile option specifies the amount of time an
OPP manager waits for the OPP to respond to its request for post processing.


Runtime properties

Set the runtime properties


Function: Home > Administration > Configuration > General > Temporary Directory

Enter the directory path for the temporary directory used by the FO Processor
when processing large files.


This is required to avoid "Out of Memory" errors.

Tip: The Database Administrator should create a cron job that will delete these files on a
regular basis. Once the output is created, the files stored in this directory are no longer
required.

FO Processing and RTF Template Properties


Function: Home > Administration > Configuration > FO Processing

Use XML Publisher's XSLT processor - Controls XML Publisher's parser usage. If set to
True, XSLT will be parsed.

Enable scalable feature of XSLT processor - Controls the scalable feature of the XDO
parser. The property "Use XML Publisher's XSLT processor" must be set to "True" for this
property to be effective.


Enable XSLT runtime optimization - When set to "True", the overall performance of the
FO processor is increased and the size of the temporary FO files generated in the temp
directory is significantly decreased.

To further enhance performance when you set this property to True, it is recommended that
you set the property Extract attribute sets to "False". See RTF Template Properties below

RTF Template Properties

Extract attribute sets - The RTF processor will automatically extract attribute sets within
the generated XSL-FO. The extracted sets are placed in an extra FO block, which can be
referenced. This improves processing performance and reduces file size.


POSSIBLE DEVELOPMENT ISSUES

The issues mainly fall within the following categories

 Environment issues – issues with setting up the environment
 Coding issues – the concurrent program does not complete successfully
 Output Post Processor (OPP) issues - the OPP does not complete successfully

To resolve an issue view the log from the concurrent program

Check the Log file details

From the view requests window, select the View Log button.

In the above example there was an invalid identifier in the where clause.

where

vi.flex_value_set_id = :PVSETID

and vit.flex_value_id = vi.flex_value_id + 0

and vit.language = userenv ('LANG')

and ad.flex_value_set_id = :VSETID

and vd.parent_flex_value_low = vi.flex_value


and vd.enabled_flag = l1.lookup_code

and vdt.flex_value_id = vd.flex_value_id + 0

and vdt.language = userenv('LANG')

and l1.lookup_type = 'YES/NO'

Output Post Processor (OPP) Issues

Concurrent Requests complete with warning

After running the concurrent program, it could complete with a warning status. This is most
likely caused by an OPP error. For example the OPP is not running or does not pick up the
request.

Solutions:

 Verify that the Output Post Processor is enabled and active.
 If confirmed, retrieve the OPP log file.


Viewing the OPP log files


Navigation: Concurrent > Manager > Administer

1. Select the Output Post Processor
2. Click on the Processes button
3. Select the Concurrent Process that was active during the time that the request ran
4. Click on the Manager Log button to open the Output Post Processor log file


Template code: ACME_GLXRLSEG_XML

Template app: SQLGL

Language: en

Territory: 00

Output type: EXCEL

... 17 more

The log file can also be retrieved via the Oracle Application Manager.

The Error Log should be passed on to the developer or the DBA, depending on the type of
issue.

The Output Post Processor is running but has not picked up the request

By default a timeout will occur if it takes longer than 120 seconds (2 min.) for the Output Post
Processor to pick up the request from the Concurrent Manager process. In that case, the
Concurrent Request will complete with status Warning and the Request log file will contain
error message like below.

...

+————- 1) PUBLISH ————-+


The Output Post-processor is running but has not picked up this request. No further
attempts will be made to post-process this request, and the request will be marked
with Warning status.

Setting the profile option Concurrent: OPP Response Timeout to a higher value may
be necessary.

+————————————–+

…

Solutions:

 Increase the value (in seconds) for the profile option ‘Concurrent:OPP Response
Timeout‘.

The concurrent manager has timed out waiting for the Output Post-processor to
finish this request

The concurrent manager process has successfully invoked the OPP but it a timeout is
encountered as the OPP takes too long to complete the job.

…

+————- 1) PUBLISH ————-+

The concurrent manager has timed out waiting for the Output Post-processor to
finish this request.

Check that there are enough Output Post-processor service processes running. More
information may be found in the service process logfile.

+————————————–+

…

The time that this takes will depends on various elements such as:


 Size of the XML Data File
 Complexity of the template
 Performance of the server

By default a timeout will occur if it takes longer then 300 seconds (5 min.) for the XML
Publisher engine to generate the output file. The Concurrent Request will complete with
status Warning and the Request log file will contain error message like above.

Solutions:

 Increase the value (in seconds) for the profile option ‘Concurrent: OPP Process
Timeout’.
 Increase the Java heap size for the report
 Setting the profile option Concurrent: OPP Response Timeout to a higher value may
be necessary. Set it to little higher value...
 Set the temp dir for XMLP
 Enable the scalability of the XSLT processor

Properties > FO Processing > Use XML Publisher’s XSLT processor / Enable scalable feature of
XSLT processor = true.

See the section on environment setup on how to perform the above. Setting the above
should resolve the issue.

If Error persists - Check the OPP log file for more information
