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...
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 里右键新建一个权限控制对象。 在创建向导里,选择 defineRoleWithPFCGAspect 的模版。这里能看到 ABAP CDS View 的权限控制对象,其定义手段是...
到了SAP云平台ABAP环境上,因为我们无法访问SAP GUI,所以要实现同样的效果,无法直接照搬上述步骤。幸运的是,在云上进行CDS view暴露的步骤依然简洁,整个过程5分钟就能搞定。 用ABAP Development Tools像登录On-Premises ABAP系统那样登录ABAP云环境,新建一个Service definition: 在Service的实现体里,使用关键字expose将ABAP...

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 ...
