在常规的ABAP CDS内我们可以使用CONCAT函数,但是使用它的时候,我们需要定义固定数量的字段,既然CDS视图不能实现此处需要的处理动态逻辑,要如何处理呢? 这是一个使用ABAP CDS Table Function的绝佳场景,因为我们可以使用简单的数据库函数STRING_AGG(String Aggregation)。这个功能在SQL Script中可用,但是目前还是不支持ABAP...
The CDS source code of a CDS table function does not need to have the same name as the CDS table function, but it is advisable to use the name of the CDS table function. After a piece of CDS source code is transported, the combination of its name and the name of the CDS table fun...

A CDS entity can be used with input parameters as one of the following: Data source or in a path expression of a different CDS view as a data source of a SELECT statement from Open SQL in ABAP In these cases, each input parameter must be assigned a suitable actual parameter whose value...
If you access a CDS view or CDS table function with parameters annotated as such in Open SQL, you can (and for #CLIENT you even must) leave away the explicit parameter passing. Open SQL implicitly passes the contents of the respective system fields for you! Example View @AbapCatalog.sqlVie...
