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://…

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:/…
