如下图所示,刚刚创建好的 CDS View,还没为其创建权限控制对象,所以收到一条警告信息: No access control for entity Z_C_SPFLI. 此时使用 ABAP OPEN SQL 或者直接在ABAP Development Tool里预览该视图,能够显示 SPFLI 数据库表的全部内容,因为此时没有定义任何的权限控制逻辑。 在ABAP Development Tool 里右键新...
Specify the source of the value help. This works a bit like a join: You need to point to an entity, and field common to both the entity and your CDS view. In this case, you will point toAgencyIDin the CDS entity/DMO/I_Agency. Add the following annotation to your fieldAgencyID. C...
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...
You have run the transactionSEPM_DG_OIA_NEWor transactionSTC01 -> tasklist SAP_BASIS_EPM_OIA_CONFIG. (If you do not, your CDS view will display empty.) Tutorial: TutorialCreate an ABAP Package In this tutorial, you will create an ABAP Dictionary-based CDS view. As of ABAP AS 7.57, su...
In part1 of this tutorial, the old way to create OData service on top of CDS view is introduced. In SAP Help Generate Service Artifacts From a CDS View a new annotation is described:@OData.publish:…
SAP ABAP 权限控制的入门级介绍 上面这篇文章,最重要的两个概念是 ABAP Authorization Object 和 PFCG Role. 在SAP 旗舰级产品 S/4HANA 里,Virtual Data Model(VDM)是极其重要的建模工具。 VDM 的重要组成部分就是 CDS View. SAP S/4HANA Virtual Data Model 介绍系列之一:CDS View 的详细分类 ...
我们在ABAP Development Tool里编写SAP CDS view,为视图维护这些以@开头的注解,同Java Spring里广泛应用的annotation一样,都是一种为development object维护元数据的方式。 如上图所示,我维护了五个不同的注解,一旦保存,这个cds view的源代码被发送到ABAP后台,通过CL_DD_DDL_HANDLER解析,DDL此处是Data Definition Lan...
在ABAP Development Tool 里激活这个 Access Control 对象之后,原本 CDS View 的语法警告消息消失了。取而代之的是另一条提示消息: The entity Z_C_SPFLI is used in DCL document ZAC_SPFLI_AUTH. 意思是如今视图 Z_C_SPFLI 的权限控制,已经被 ZAC_SPFLI_AUTH 接管了。
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 ...
https://blogs.sap.com/2016/03/12/my-cds-view-self-study-tutorial-part-4-how-does-annotation-odatapublish-work/ 加上这个注解的CDS view,一旦激活后就会在ABAP Netweaver自动生成一个OData服务,在事务码/IWFND/MAINT_SERVICE里将其搜索出来并添加,就能够以OData服务的方式,消费这个view暴露出来的数据了。
