S4/HANA里有一个新的UI框架叫做Smart template, 配合ABAP后台的CDS view技术,能够让developer以Metadata driven的方式来开发Fiori应用, 这种开发方式几乎不需要或者只需要很少量的JavaScript开发. 下面是我写在SCN上的相关13篇blog的链接: Step by Step to create CDS view through SmartTemplate + WebIDE Currency example - how Smart f…
来自我的同事Xu Miles Authorization Objects are business concept, they are distinguished by business scenario. Therefore, there might be a lot of Authorization Objects using the same Authorization Field. Such as VKORG. In Sales Planning, there're two Author…
In the Part 1 blog, we have discussed below topics CDS annotations for Fiori List Report. How to create a Gateway service from ABAP CDS view How to create a Fiori List App report in Web IDE. How to Deploy the Fiori Application. In this blog, we are g…
Syntax ... @annotation ... Effect Specifies Annotation annotation in the definition of a CDS view of the ABAP CDS before statement DEFINE VIEW. The character @ must be placed before the name annotation of the annotation. The table below shows the pos…
According to this wiki, write back on CDS view is not supported: And also it is defined in ABAP help that only read operation is supported. For other operation like write, you have to still use original database table. Test on write operation attempt…
Scenario Suppose we have a database table A, and then we create a CDS redirect view B for it, then every time the READ OPEN SQL is done on table A, ABAP kernel will direct this request to view B, and serve the request with content from B. Prerequisit…

动机 现在大家都知道单元测试对我们代码的好处.并且我们都承认它是开发过程中不可或缺的一部分.但是在把代码切换到数据库的模式下的时候,我们被粗暴地打回了软件测试的黑暗年代...我们现在面临着逻辑下推到ABAP CDS entities后,代码要如何测试的难题. CDS Test Double Framework允许开发者们通过众所周知的ABAP Unit Test Framework自动化地测试CDS entities. 本文链接:http://www.cnblogs.com/hhelibeb/p…
The syntax of the DDL and of the DCL of the ABAP CDS comprises elements of the general DDL and DCL of SQL. In addition, the syntax makes it possible to define annotations and associations. The syntax and semantics basically match the general CDS conc…

如管理学学者彼得·德鲁克所说:你无法管理你不能衡量的东西( If you can't measure it, you can't manage it).要对已有程序进行性能优化,首先要对它的运行状况做出量化分析. 将代码下推到ABAP CDS,是SAP推荐的一种优化方式.但正因逻辑从应用服务器向数据库的转移,传统运行时分析工具SAT也有了力所不能及之处.这时,我们需要新的工具来对这一新的开发对象的运行情况进行分析. 本文将介绍Plan Visualizer(以下简称PlanViz)在ABAP C…
Association in ABAP CDS An association in CDS view joins different data sources. Defining and using associations is a high-value wrapping of the syntax for joins. A CDS View with association between SPFLI & SCARR table. @AbapCatalog.sqlViewName: ‘ZFL…
