For example, create a new CDS view in ABAP development studio and paste the following source code, @AbapCatalog.sqlViewName:'zstatustext'@AbapCatalog.compiler.compareFilter:true@AccessControl.authorizationCheck:#CHECK@EndUserText.label:'system status code and description'defineviewZ_C_Status_Textass...
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...
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...
可以在HANA STUDIO中创建一个程序,创建方法参看:何在HANA上的ABAP程序中调用ABAP CDS视图,创建程序完成后,程序代码如下: ABAP SELECT orderno, itemno, currency, grossamount, netamount, bill_status FROM z_cds_params( p_billing_status = 'P', p_delivery_status = 'D' ) INTO TABLE @DATA(lt_result)...
在SAP 的 ABAP 编程环境中,CDS(Core Data Services)视图是一个强大的工具,可以让开发者以更高效、更简洁的方式操作数据库。在 CDS 视图的源代码中,$projection是一个特殊的关键字,它被用来引用当前的投影列表。也就是说,$projection引用的是当前 CDS 视图定义中所包含的所有字段。
SAP Managed Tags: ABAP Development With ABAP release 7.55, a new type of CDS view is available: in official terminology, it's called CDS view entity. And it has come to replace the "classic" CDS DDIC-based views that have been around for years. This blog post provides the following in...
you can realize that lots of database tables “DD*” are involved during CDS view activation, for exampleDDLDEPENDENCY. A small tip here is, if you click “Display Object List” button, you will navigate to the package where other related ABAP artifacts within the same package are displayed...
SAP Fiori的ABAP编程模型-CDS视图创建 让我们开始为我们的应用程序创建数据模型。通常,最佳做法是创建一个Package并封装将由CDS视图创建的数据模型。 一、创建一个包:使用SE80事务并创建一个包装,如下所示; 二、使用CDS视图创建数据模型 让我们假设航空业场景的数据模型。航空业将获得与航空公司有关的信息和航班旅行...
1. 正则表达式测试程序 DEMO_REGEX DEMO_REGEX_TOY 2. ABAP SQL & CDSView Entity支持正则语法的场景 ## 3. 用法 LIKE_REGEXPR 取工厂为纯数字的数据(ABAP SQL) SELECT * FROM marc WHERE LIKE_REGEXPR( PCRE = '[0-9]{4}',VALUE = werks,CASE_SENSITIVE = ' ' ) = 1 ...
CDS is a central part of enabling code push-down in ABAP applications. You can find more information about these deprecated CDS Views here:- ABAP keyword documentation, version 7.51: CDS Views You can find more information about CDS View Entities here:- https://help.sap.com/doc/abapdocu_...
