Web Transaction API

Use

The Application Programming Interface (API) for Web transactions consists of ABAP macros and function modules for developing Web transactions, also known as Internet Application Components (IACs). These are programmed based on the implementation model for Web transactions.

You can use these macros and function modules in ABAP programs to import data from, and export data to, a Web browser using the Internet Transaction Server (ITS).

The Web Transaction API supports the transfer of context fields and Multipurpose Internet Mail Extension (MIME) data between transactions in the SAP system and their Internet-enabled versions displayed in a Web browser.

Prerequisites

To use the macros and function modules of the Web Transaction API, you must include the module avwrtcxm in the ABAP program.

Example:

        
program sapmpw02. include avwrtcxm.
