Integrating Separate Customer Functions 

Use

You would like to enhance SAP Biller Direct with your own functions.

Prerequisites

Such enhancements presuppose considerable experience in the area of Java programming.

To include your own Java code in the application, you need a Java development environment, meaning an editor, compiler and if necessary a debugger. To be able to compile your own or the example source code, you have to make all of the SAP J2EE Engine libraries accessible from directory additional-lib in addition to the libraries that belong directly to Biller Direct that are contained in directories WEB_INF/lib: ebpp.jar and webbase.jar when you set up the development environment.

Activities

The following shows you how to implement your own functions using the framework, and how you can access data from the core application.

The SAP Biller Direct delivery contains example code for customer-defined enhancements in the .ear file that you can use as template for implementing your own functions.
After you have unpacked the application as set out in the implementation guide, you can find folder \docs\customerExtensions Beispielsourcecode. Based on this example that you can use to display a list of all of the company codes with their relationships taken from the ERP system, the following sections demonstrate step by step how to integrate an enhancement in your installation.
