The ABAP Core Data Services (ABAP CDS) framework has been available since NetWeaver 7.40 SP05 and offers highly attractive features & benefits, e.g.:

  • Many new SQL features:


    • SQL set operations: UNION, UNION ALL

    • SELECT clauses: GROUP BY, HAVING

    • Aggregate functions: AVG, MAX, SUM, ...

    • Numeric functions: CEIL, MOD, ABS, ...

    • String functions: SUBSTRING, LPAD, CONCAT, ...

    • Date and time functions: DATS_DAYS_BETWEEN, DATS_ADD_DAYS, ...

    • ...

  • Easy-to-integrate services on-top:

    • OData clients

    • SAP Fiori

    • Analytics

  • Simplification of application coding

  • Push-down of workload into the database

Since the technology is fairly new it poses quite some challenges to you as system administrators or development teams. You need to

  • ensure that the maintenance level of their software stack is up-to-date,

  • keep an eye on the overall CDS work load,

  • monitor and tune the performance of complex queries, and

  • establish clear rules for the development of own code using CDS.

Fortunately, a best practice guide is now available on how to implement, monitor and tune CDS based applications in Business Suite systems. All supported databases types are covered (IBM Db2, Oracle, MS-SQL, SAP ASE, SAP MaxDB & SAP HANA DB). The document provides an holistic approach to CDS and is written for IT architects, ABAP developers, SAP Basis teams and database administrators. Regular updates are planned.
