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…

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…

如果你在网络或者SCN上面搜索CDS,即SAP的Core Data Services,你会很容易地找到类似“Core Data Services(CDS)是一个在SAP HANA中用于定义和消费富语义数据模型的基础架构”这样的句子.在另一方面,在ABAP字典中似乎也有一种叫做ABAP CDS的东西.它们有什么关系?让我们从ABAP(还有ABAP CDS)文档的作者的视角中看看这个问题. 原文标题:CDS – One Concept, Two Flavors 本文链接:http://www.cnb…

Hi! 对每一个CDS视图,我们都可以通过DCL(Data Control Language)定义访问控制.在这篇文章中,我会介绍ABAP CDS视图中非常重要的一面:权限管理. 本文的阐述基于我正在使用的S4/HANA 1610 on NW 7.51. 内容分为五个部分: 标准示例的访问控制. 基于PFCG权限创建一个简单的例子. 带有CUBE数据类别的CDS分析视图. CDS分析查询视图的访问控制. 权限对象的并集(UNION)或者交集(INTERSECTION). 本文链接:http://…

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…

Core data services(以下简称CDS)可以指两样东西,一个是HANA CDS,一个是ABAP CDS. 如我们所知,HANA CDS只支持HANA数据库,ABAP CDS理论上支持多种数据库供应商,结果是,ABAP CDS相比之下要少一些功能.因此,在某些情况下,无法使用ABAP CDS解决问题时,可以使用一种变通的方法,即通过ABAP Managed Database Procedures (AMDP)创建ABAP CDS Table Function. 本文链接:http:/…
