在定义CDS时会有几个对象名容易混淆,如果你只想知道怎么用,不在乎原理,记得每次用Open SQL时,From后面只跟Define view后面的那个ID就低了,可以跳过此节。如果你想了解清楚其差异(其实也没什么用),请继续 如上图所示(图片来自于help.sap.com),在定义CDS时,整段的代码,叫做DDL source,第一个Annotation:AbapCatal...
@ObjectModel.readOnly: true Z_i_Order_View.posting_date We can also look into another example. We have use the following annotation “@Consumption.valueHelp: ‘_statusfixedvalue’ ” to assign a value help to field txt04: @Consumption.valueHelp: ‘_statusfixedvalue’ Z_i_Order_View.txt04,...
比如,如果您在 CDS View 中引用了 sales_order 实体中的 order_id 字段,确认该字段确实存在于该实体中。 使用正确的注解和语法 CDS View 中的注解(Annotation)和 DDL 语句需要正确使用。例如,如果您想让您的 CDS View 支持 OData 服务,需要使用 @OData.publish: true 注解。确保所有注解都是放在正确的位置,并...

the label of a DDIC element for all my CDS view I use a element of this type: In this case I define a CDS Type with this annotation @EndUserText.label: 'myLabel' define type myType: ddic_type and then I can cast the data element cast ( _data.attribute as myType) as attribute;...
Annotations are checked to ensure that only annotations defined as CDS objects in a CDS annotation definition can be used. Expressions can be nested within each other. Situations that previously required a view stack can now be implemented within a single view. ...
