Overview of Using Siebel Visual Basic and Siebel eScript

You can use Siebel VB or Siebel eScript to customize and configure Siebel CRM beyond the capabilities that defining object properties provides. These languages integrate with other Siebel tools, such as the Applet Designer, Siebel CTI, and Siebel SmartScript. To define object properties, you can use the Applet Designer or attach scripts.

It is recommended that you use coding only after you determine that you cannot use any other tool. Siebel Tools provides many ways to configure Siebel CRM without coding. The following reasons explain why you must use Siebel Tools before you write your own code:

• Using Siebel Tools is easier than writing code.
• Your code might not work with an upgrade. Siebel CRM automatically updates a customization that you create in Siebel Tools during an upgrade. It does not update custom code you create. It might be necessary for you to manually update the code.
• Configuration through Siebel Tools results in better performance than using the same features through code. For more information, see Siebel Performance Tuning Guide.
