CDS examples

Quick answer

CDS models data close to the database with reusable, annotated views.

Key takeaways

  • Watch out: Ignoring annotations that unlock OData/analytics.
  • Worked examples: a cds view with an association, aggregation and annotations, what it teaches.
  • How CDS examples fits into SAP development and the wider SAP landscape

A CDS view with an association

define view entity Z_SalesDoc as select from vbak
  association [1..*] to vbap as _Item on vbak.vbeln = vbap.vbeln
{
  key vbak.vbeln,
  vbak.kunnr,
  _Item
}

Aggregation and annotations

@Analytics.dataCategory: #CUBE
@OData.publish: true
define view entity Z_Sales_Cube as select from I_SalesOrderItem {
  key SoldToParty,
  @Aggregation.default: #SUM
  NetAmount
}

What it teaches

CDS models data close to the database with reusable, annotated views. Annotations turn a view into an OData service, an analytical cube, or UI metadata, one model, many uses. Layer base and composite views, and push filtering/aggregation down for performance.

Common pitfalls

  • Ignoring annotations that unlock OData/analytics.
  • Monolithic views.
  • Late aggregation hurting performance.
