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。 CDS(Core Data Service)是SAP的战略性的技术解决方案之一。其目的是在数据的物理存在和用户需求中间构建起一个虚拟层,满足用户对访问SAP系统数据的需求,CDS的设计具...
So i guess it is not possible have a dynamic calling of table functions with parameters from an CDS view. How would you handle this? Table function: > define table function Z_WH_EDDATE_TABLE_FUNCTION with parameters > @Environment.systemField: #CLIENT > clnt :abap.clnt, > ebeln_param :...
CDS Entity ZCDS_VIEW定义了一个到数据库表scustom的投影。生成的SQL View(ZcdsView)包含了所有选取的字段id,name,city. 激活 激活CDS View后,在ABAP字典中会创建以下对象: 实际的CDS Entity (Zcds_View) SQL View (ZcdsView) b.ABAP CDS Table Functions 使用ABAP CDS声明语句DEFINE TABLE FUNCTION可以定义...

(2) When we test read & search function against the odata service created on top of the CDS view, the operation is delegated to CL_SQL_STATEMENT~EXECUTE_QUERY. And now I ask myself, since what we have typed in Eclipse is pure text, how does ABAP backend interpret the text and convert...
The following table shows the SQL functions for strings supported by ABAP CDS and Open SQL. The last two columns indicate where a function can be used. The following can be specified as the arguments arg: Literals of a suitable type. The literal can be prefixed with the name of a domain...
在 ABAP 编程中,理解类、方法和内置函数之间的关系对于编写高效、可维护的代码至关重要。你提到的这句话 Within a class, a built-in function is always obscured by methods of the class if they have the s…
Of course, a real CDS table function would do more HANA specific things (e.g. wrapping a HANA function) than a simple join as shown in the simple example here! A join you can code also in Open SQL or in a CDS View. Speaking about Open SQL, last but not least, the usage of our...
