Path Expression是SAP CDS View中的一个重要概念,用于在数据模型中定义字段之间的关系和连接。它允许用户在一个CDS视图中引用另一个CDS视图,并建立它们之间的关联。通过使用Path Expression,用户可以在查询中轻松地访问和检索相关的数据,而无需手动编写复杂的SQL连接语句。 Path Expression的作用 Path Expression在SAP CD...

We can read and write the CORE-V’s registers in the “Register View”, To access the variables of the program, we should use “Variable view”. In the “Expression View”, we can input any variable or symbol of our project, and read it or modify it. ...
Associations that could be followed at runtime by using explicit path notation in an SQL access are not counted. There are of course many more factors that contribute to the complexity of a CDS view: join and union operations, CASE expressions, functions and calculations, aggregations, and ...
