API for Amazon Simple Workflow Service¶
|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 Amazon Simple Workflow Service 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 SWF 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¶
The Amazon Simple Workflow Service (Amazon SWF) makes it easy to build applications that use Amazon's cloud to coordinate work across distributed components. In Amazon SWF, a task represents a logical unit of work that is performed by a component of your workflow. Coordinating tasks in a workflow involves managing intertask dependencies, scheduling, and concurrency in accordance with the logical flow of the application.
Amazon SWF gives you full control over implementing tasks and coordinating them without worrying about underlying complexities such as tracking their progress and maintaining their state.
This documentation serves as reference only. For a broader overview of the Amazon SWF programming model, see the Amazon SWF Developer Guide .
Using the SDK¶
In your code, create a client using the SDK module for Amazon Simple Workflow Service, 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_swf) = /aws1/cl_swf_factory=>create( go_session ).

TYPE REF TO
/AWS1/IF_SWFrepresents the ABAP client for the SWF service, representing each operation as a method call. For more information see the API Page page.
DATA(lo_config) = DATA(go_swf)->get_config( ).
Paginators for Amazon Simple Workflow Service can be created via
get_paginator() which returns a paginator object of type
/AWS1/IF_SWF_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
