About The Service

Amazon Lex Build-Time Actions

Amazon Lex is an AWS service for building conversational voice and text interfaces. Use these actions to create, update, and delete conversational bots for new and existing client applications.

Using the SDK

In your code, create a client using the SDK module for Amazon Lex Model Building Service, which is created with factory method /AWS1/CL_LXB_FACTORY=>create(). In this example we will assume you have configured an SDK profile in transaction /AWS1/IMG called ZFINANCE.

DATA(go_session)   = /aws1/cl_rt_session_aws=>create( 'ZFINANCE' ).
DATA(go_lxb)       = /aws1/cl_lxb_factory=>create( go_session ).

Your variable go_lxb is an instance of /AWS1/IF_LXB, and all of the operations in the Amazon Lex Model Building Service service are accessed by calling methods in /AWS1/IF_LXB.
