# 使用 SDK for SAP ABAP 的 Amazon S3 示例
<a name="sap-abap_s3_code_examples"></a>

以下代码示例向您展示了如何使用适用于 SAP ABAP 的软件开发工具包和 Amazon AWS S3 来执行操作和实现常见场景。

*基本功能*是向您展示如何在服务中执行基本操作的代码示例。

*操作*是大型程序的代码摘录，必须在上下文中运行。您可以通过操作了解如何调用单个服务函数，还可以通过函数相关场景的上下文查看操作。

*场景*是向您演示如何通过在一个服务中调用多个函数或与其他 AWS 服务结合来完成特定任务的代码示例。

每个示例都包含一个指向完整源代码的链接，您可以从中找到有关如何在上下文中设置和运行代码的说明。
