To create a new business component

To add a business component to a business object

Introduction

Siebel-provided business components cover most of the commonly

used business entities, but not all the possibilities

Example: An organization might want to capture personal data for

their contacts, like:

What colleges the contact attended, including information such as nameof college, major field of study, university, etc

What are the contacts culinary likes and dislikes

Capturing this kind of information may require:

Multiple fields to capture the details

1:M or M:M relationship with the parent


5/22


Solution Create New BCs

To capture such information, create new BCs

For example, for the Contact parent BC, create College and Tastes child

BCs

These BCs may be based on tables supplied by Oracle

Standard

Extension 1:M

M:M


6/22


1:M Relationship with Existing Table

College and Tastes have a 1:M relationship with the Contact BC

Hence, two new BCs are required, one for College attended and the other

for culinary Tastes

When creating a BC which has a 1:M relationship with the parent BC,

use a 1:M extension table

College Contact Tastes

Standard 1:M Extension Tables

Many business components have standard 1:M extension tables

defined for them The extension table has name derived as parent table name

appended with _XMPredefined

ATTRIB

columns of

varying types

NAME

column stores

the name of

the child

entityPAR_ROW_ID

column stores

foreign key to

ROW_ID in main

table

TYPE

identifies the

child BC



User Key for Extension Table

NAME, PAR_ROW_ID and TYPE serve as the user key for theextension table

These three are required columns. Their combined value must be unique for

a record

ROW_ID

NAME

PAR_ROW_ID

TYPE

S_OPTY_XM

User Key



Business Component Wizard

The Business Component wizard is used to create a new business

component Select File > New Object, then select BusComp and click OK



Business Component Wizard Inputs

The following inputs are required for the business component wizard:

The project the new BC will be a part of

Name of the new BC

The BCs table name

Fields that will be part of the BC

Selected in the wizard by specifying Table Column and then the fieldname

Specify TYPE column and relate it to Type field

Specify PAR_ROW_ID column and relate it to Id field

Specify NAME column and relate it to Name field

For additional data, use ATTRIB columns

Use a separate column for each field

Columns are limited by the table one selects for the BC



Business Component Wizard Outputs

The business component wizard creates:

A business component object and its child object definitionsFields and relates them to table columns

New BC

object

definition

created

New fields

created and

related to table

columns



Set the Pre-Default Value

Predefault value automatically assigns a value to a field for a new

record

For extension tables, set the Predefault Value property of the Type field to

the value specified in the Search Specification of the BC

Can be used to ensure that the user key is populated

Matches value

in BC Search

Specification



Set Search Specification

The search specification is set to match the unique TYPE value for

the BCSpecifies the records to be retrieved by the BC

Typically used with extension tables

Supports the case where multiple BCs are based on the same extension

table

Only records ofTYPE = College

are retrieved



Multiple Child Business Components

The same table can be used to map multiple user-defined child BCs

Each BC has a unique TYPE value

Each BC retrieves only those records with its TYPE value

College

Type = College

Tastes

Type = Taste

ROW_ID

NAME

TYPE

PAR_ROW_ID

S_CONTACT_XM



Post-Creation Tasks

1. Relate Child and Parent BCs

2. Reference Business Component in Business Object

3. Enable Display Data in UI



Relate Child and Parent BCs

Associate the newly created child BC to the parent BC:

To do this, create a link definition to relate child and parent records

Contact

College Tastes

Parent

Child Child

Contact/College

Link

Contact/Tastes

Link



Relate Child and Parent BCs

Create a separate link for each parent/child

relationshipContact/College

Contact/Tastes

This link is specified in the business object



Reference Business Component in Business Object

For each new BC created, create a Business Object Component

definitionThe business object for the parent BC is to be used

The Link property is to be setParent BC

Child BC Link



Enable Display Data in UI

To enable data display from the BC in the UI, build applets and viewsas required

Note: The Type field must not be displayed in the UI to prevent users from

changing its value


20/22


Creating a Standalone Business Component

A companys business logic may require creation of a new table in thedatabase

A standalone BC is then created whose fields reference the columns of this

new table

To create a standalone business component:

Create a new table to hold the BC dataCreate columns for the table

Create a new BC and add fields that reference the created table columns

Create a new business object and add the new BC as its component

Enable data display in the UI

Standalone BCs are based on standalone tables and have no

relationship with other BCs and tables


21/22


Module Highlights

For capturing new information, create a new BC as a child of anexisting BC

May use extension tables with name ending with _XM

When using extension tables, the same table can be used to map to

multiple child BCs

Data retrieved depends on the value in field Type, which is uniqueSpecify properties on BC and fields

Include required fields like Type and Name

Create a link definition to relate child with parent BC

Add the BC to a BO and then create applets and views to display data

Create a standalone BC based on newly created table in database, ifnecessary
