API for AWS AppConfig Data¶
|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 AppConfig Data 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 AppConfigData 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¶
AppConfig Data provides the data plane APIs your application uses to retrieve configuration data. Here's how it works:
Your application retrieves configuration data by first establishing a configuration session using the AppConfig Data StartConfigurationSession API action. Your session's client then makes periodic calls to GetLatestConfiguration to check for and retrieve the latest data available.
StartConfigurationSession, your code sends the following
Identifiers (ID or name) of an AppConfig application, environment, and configuration profile that the session tracks.
(Optional) The minimum amount of time the session's client must wait between calls to
In response, AppConfig provides an
InitialConfigurationToken to be given to
the session's client and used the first time it calls
for that session.
This token should only be used once in your first call to
GetLatestConfiguration. You must use the new token
NextPollConfigurationToken) in each subsequent call to
GetLatestConfiguration, your client code sends the most recent
ConfigurationToken value it has and receives in response:
ConfigurationTokenvalue to use on the next call to
NextPollIntervalInSeconds: the duration the client should wait before making its next call to
GetLatestConfiguration. This duration may vary over the course of the session, so it should be used instead of the value sent on the
The configuration: the latest data intended for the session. This may be empty if the client already has the latest version of the configuration.
NextPollConfigurationToken should only be used once. To support long poll
use cases, the tokens are valid for up to 24 hours. If a
GetLatestConfiguration call uses an expired token, the system returns

Using the SDK¶
In your code, create a client using the SDK module for AWS AppConfig Data, 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_apd) = /aws1/cl_apd_factory=>create( go_session ).
