API for AWS Step Functions¶
|ABAP SDK "TLA"
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
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 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
Using the SDK¶
In your code, create a client using the SDK module for AWS Step Functions, which is created with
In this example we will assume you have configured
an SDK profile in transaction
DATA(go_session) = /aws1/cl_rt_session_aws=>create( 'ZFINANCE' ).
DATA(go_sfn) = /aws1/cl_sfn_factory=>create( go_session ).
For an overview of ABAP method calls corresponding to API operations in AWS Step Functions, see the Operation List.
Creates an object of type
TYPE REF TO
TYPE REF TO
/AWS1/IF_SFNrepresents the ABAP client for the SFN service, representing each operation as a method call. For more information see the API Page page.
DATA(lo_config) = DATA(go_sfn)->get_config( ).
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
Details about the paginator methods available for service AWS Step Functions can be found in interface
