SAP ABAP CDS View 是 SAP 实现Code Push Down(也称 Code to Data) 的一种技术手段,即将部分取数逻辑,从应用服务器推送到数据库层,从而充分发挥 SAP HANA 强大的数据处理能力。 值得一提的是,虽然如上图所示,大多数时候提到 CDS View 时,都伴随着 HANA 数据库,然而 CDS View 并未和 HANA 深度绑定;ABAP ...
This tutorial provides a brief explanation of how to build Core Data Services (CDS) Views in ABAP on SAP HANA and how to display them using the ABAP List Viewer (ALV). What is CDS? CDS (Core Data Services)is a collection of domain-specific languages and services that are used for defin...
Subject: RE: have a quick discussion about why the CDS view has a bad performance displayed in ST05 or SAT but the trace displayed in HANA studio shows a good performance Thanks a lot for your support. I have executed the report repeatedly for 5 times and the average time in ABAP is st...
In ABAP layer, the limit is specified dynamically – not fixed in the design time. However in HANA studio, the limit 100 is hard coded. When I change the dynamically specified limit operation in ABAP with fixed limit, the performance in ABAP is now consistent with HANA studio: The reason ...

SAP ABAP CDS view 和和 HANA CDS view 的区别 这两种技术都是 SAP 提出的"Code pushdown"理念的具体实现。SAP ABAP CDS view 位于 ABAP 应用服务器层,使用 OPEN SQL,支持的数据库不限 HANA,因此既能在 ECC 也能在 S/4HANA 里使用;ABAP CDS view 的使命是身为 SAP ABAP 新一代编程模型的一部分,帮助...
HANA CDS的实现和ABAP CDS的实现正在以不同的优先级推进。这就是为什么像“New Core Data Services Features in SAP HANA 1.0 SPS 10”这样的的博客会面向直接在SAP HANA上工作的开发者。ABAP开发者们则不得不在“ABAP News”这样的博客里寻找相关内容。

参数类型可以是预定义的 ABAP 类型或数据元素。CDS 的预定义 ABAP 类型与 ABAP 数据字典不同,可以使用输入帮助(Ctrl + Space) 可以使用注释分配默认值 – @Environment.systemField: #SYSTEM_DATE 仅当分配了默认值时,参数才是可选的。我们只能使用系统字段,例如#SYSTEM_DATE。可能的值如下。
