Top 34 Siebel Eai Interview Questions You Must Prepare 21.Apr.2024

Workflows can be invoked using :-

  • A Workflow
  • A run-time Event
  • A script
  • The workflow process simulator ( for testing )

Importing WSDL in Siebel is two step process: 

  1. First, WSDL is imported into Siebel Tools using WSDL Import Wizard. It creates Integration objects and proxy business service from WSDL definition, and generates XML for run time data creation. 
  2. Secondly, XML generated  is then imported in to web client. Process is outlined in bookshelf here.

Siebel does not support changing the case of through EAI, however it is possible to call a custom business service through data maps which can convert the case.

InvokeServiceMethod ("CustomDataMapper", "UpperCase", "InputStr='"+[Integration Field Name]+"'", "OutputStr")

• Service_PreInvokeMethod
• Service_InvokeMethod
• Service_PreCanInvokeMethod

Name of Integration Component Field is used to create the Siebel Message property set, It is essential to know the ICF name if script is used to get value from XML.

A group of rules in a sequence, used to parse property set input until a rule is found that matches the input.


  1. Use when URL access will not change the state of the database
  2. Use to ask for a specific piece or set of information

Example: Clicking a hyperlink uses GET


  1. Use when URL access will change the state of the database
  2. Use to post a specific piece or set of information

Example: Sending information in a Web-based form uses POST.

  • Is a user interface that enables you to create data maps for outbound and inbound data transformation
  • Is declarative — little or no programming is necessary
  • Uses the EAI Data Mapping Engine business service to execute the data transformation
  • Stores data transformation maps in the Siebel database

• Changes data in a business object instance to match data in an integration object instance.
• Updates, inserts, or deletes a business component instance.

Use EAI Siebel Adapter Business Service Query method and then EAI XML Converter Service Method HierToDoc to generate XML Doc.

Find the Integration Component Field and update the External Field name to the new field name.

Reads a file and transforms data from an XML format to a property set format.

Performs a combination of operations on components of an integration object instance.

Find the Integration object from the xml and then go to the desired integration component and update the XML Tag of desired integration component field.

WSDL stands for Web Services Descriptive Language. It is an XML file which describes everything about a web server. 

Typically it contains:

  • Web service end point (URL)
  • Methods web service Support
  • Input and output arguments.
  • WSDL is technology/platform independent syntax thus it is widely accepted way of describing web services definition.

  • A workflow process
  • A method from another business service
  • A user interface event
  • A Siebel object interface ( COM , CORBA , Java )

Deletes a business component instance.

XSD is an XML Schema Definition document. It is a type of XML document which defines the structure of an XML document. It contains the structure of the XML and the data type and length of XML.

Siebel tools can generated by Generate XML Schema wizard by clicking Generate Schema Button. 

  • A search expression to evaluate incoming data, plus
  • A business service and method to send data matching the criteria

Selects data from the Siebel database Without using Siebel object interfaces.

To export Siebel data to an external system we can use either one of the following solutions.

  • Enterprise Integration Manager ( EIM )
  • Object Interface
  • Workflow for EAI (Outbound)
  • EAI Dispatch service (Outbound )

Transforms data from a property set to an XML format and writes it to a file.

• Query
• Upsert
• Delete
• Synchronize
• Execute

Internal Integration Object refers to Siebel Business Object for querying and saving data. External Integration Object refers to XML schema, one can not use query or insert operation on external integration object. To create external integration object, either XSD or DTD document is required.

DTD is Document Type Definition, it is another form of document which describes the structure and data types of an XML document. It can also be generated through Generate Schema Button on the Siebel Integration Object.

Integration objects enable the transformation of application-specific data into a common format (such as XML) that other applications can process.

  • A specification of a target format for the output property set, plus
  • A specification of the source data in the output property set

To control a Siebel application from an external system we can use either one of the following solutions.

  • Workflow for EAI
  • Object Interface

Notation that defines a rule, a subset of the XPath standard.

  • Sends/receives XML messages across the Internet to or from a port using Hypertext Transfer Protocol (HTTP)
  • Can send messages beyond corporate boundaries to Web-based applications written in Java, JavaScript, VBScript, or another Web-enabled technology
  • Transports messages in XML format by default
  • Provides synchronous connectivity
  • Supports all inbound and outbound transport methods
  • Runs within the Siebel Object Manager

  • Defines the relationship between the source and target format
  • Directs the mapping and transformation process

• An event is a user or system action to which the Siebel application might respond
Select events are exposed through the Application Programming Interface (API)

Example: Updating a record, updating a field, and deleting a record

• An event handler is the Siebel code that executes in response to the event

Example: When the user steps off a record being edited (the event), the application responds by committing the record to the database (the event handler)

XML container element if specified on IC then Siebel adapter will always create an XML tag before the start of child IC records, and it will always be present in XML even if no records are returned by query method.

• An integration object is metadata. A model of the structure of a particular data set.
• Whereas an integration object is metadata. A model of the structure of a particular data set.
