cl_salv_gui_table_ida=>create_for_cds_view(iv_cds_view_name='ZFAT_INTERFACE')->fullscreen()->display(). 这个CDS view显示的数据,是当前ABAP系统里所有的接口(SE24里查看的interface)和接口上定义的方法个数。 CDS view实现源码如下: 为什么要搞这样一个CDS view出来?Jerry曾经给SAP成都研究院的同事们...
Perform a SQL trace with tcode ST05, display execution plan via menu below: You can find there is a fragment of WHERE statement automatically added. The value for ORDER_TYPE comes from the value of authorization object field PR_TYPE which is mapped to CDS view field ORDER_TYPE in my DCL ...

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 ...
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。
EndUserText.label: 'Sample CDS View' define view ZCDS_VIEW ``` - 视图字段列表:在CDS View中定义要查询或显示的字段,示例代码如下: ``` { key field1, field2, field3 } ``` - 关联数据表:CDS View可以关联一个或多个数据表,以便进行数据查询和操作,示例代码如下: ``` association [0..1] to...

选择了具体的extension field之后,再选择要extend的CDS view,点击publish,此时将会自动创建一个带有当前extension field的extension view,对选中的CDS extensible view进行扩展。这样造成的结果是,从SE11里观察SQL view能发现extension field会通过append的方式直接成为extensible view的一部分,这之后和E_PRODUCT再无任何关系...
