To create an extension table to an interface table in Siebel, follow these steps:
1. **Identify the Interface Table**: Determine the existing interface table you want to extend.
2. **Create the Extension Table**: In the database, create a new table that includes a foreign key referencing the primary key of the interface table.
3. **Define the Extension Table in Siebel**:
- Go to the Siebel Tools.
- Create a new table definition for your extension table.
- Set the properties, including the foreign key relationship to the interface table.
4. **Add Fields**: Add the necessary fields to the extension table as per your requirements.
5. **Compile the Changes**: Compile the project in Siebel Tools to apply the changes.
6. **Test the Integration**: Ensure that the extension table is correctly linked and functioning with the interface table in the application.
Make sure to follow best practices for naming conventions and data types.
