API for AWS Step Functions

ABAP Interface /AWS1/IF_SFN

The "TLA" is a Three Letter Abbreviation that appears in ABAP class names, data dictionary objects and other ABAP objects throughout the AWS SDK for SAP ABAP. The TLA for AWS Step Functions is SFN. This TLA helps squeeze ABAP objects into the 30-character length limit of the ABAP data dictionary.


To install the AWS SDK for SAP ABAP, import the Core transport, along with the transport for the SFN module and other API modules you are interested in. A few modules are included in the Core transport itself. For more information, see the Developer Guide guide.

About The Service

Step Functions

Step Functions is a service that lets you coordinate the components of distributed applications and microservices using visual workflows.

You can use Step Functions to build applications from individual components, each of which performs a discrete function, or task, allowing you to scale and change applications quickly. Step Functions provides a console that helps visualize the components of your application as a series of steps. Step Functions automatically triggers and tracks each step, and retries steps when there are errors, so your application executes predictably and in the right order every time. Step Functions logs the state of each step, so you can quickly diagnose and debug any issues.

Step Functions manages operations and underlying infrastructure to ensure your application is available at any scale. You can run tasks on Amazon Web Services, your own servers, or any system that has access to Amazon Web Services. You can access and use Step Functions using the console, the Amazon Web Services SDKs, or an HTTP API. For more information about Step Functions, see the Step Functions Developer Guide .

If you use the Step Functions API actions using Amazon Web Services SDK integrations, make sure the API actions are in camel case and parameter names are in Pascal case. For example, you could use Step Functions API action startSyncExecution and specify its parameter as StateMachineArn.

Using the SDK

In your code, create a client using the SDK module for AWS Step Functions, which is created with factory method /AWS1/CL_SFN_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_sfn)       = /aws1/cl_sfn_factory=>create( go_session ).

Your variable go_sfn is an instance of /AWS1/IF_SFN, and all of the operations in the AWS Step Functions service are accessed by calling methods in /AWS1/IF_SFN.

API Operations

For an overview of ABAP method calls corresponding to API operations in AWS Step Functions, see the Operation List.

Factory Method

/AWS1/CL_SFN_FACTORY=>create( )

Creates an object of type /AWS1/IF_SFN.


Optional arguments:







/AWS1/IF_SFN represents the ABAP client for the SFN service, representing each operation as a method call. For more information see the API Page page.

Configuring Programmatically

DATA(lo_config) = DATA(go_sfn)->get_config( ).

lo_config is a variable of type /AWS1/CL_SFN_CONFIG. See the documentation for /AWS1/CL_SFN_CONFIG for details on the settings that can be configured.


Paginators for AWS Step Functions can be created via get_paginator() which returns a paginator object of type /AWS1/IF_SFN_PAGINATOR. The operation method that is being paginated is called using the paginator object, which accepts any necessary parameters to provide to the underlying API operation. This returns an iterator object which can be used to iterate over paginated results using has_next() and get_next() methods.

Details about the paginator methods available for service AWS Step Functions can be found in interface /AWS1/IF_SFN_PAGINATOR.
