Smart SAP Assistant

• What is the cause and solution for SAP error message DDLS330 - Basis object & is external view. CDS view thus only available on HANA DB. ?

  The SAP error message DDLS330 indicates that you are trying to create or modify a Core Data Services (CDS) view that is defined as an external view, but the underlying database is not HANA. This error typically arises when you attempt to use features or functionalities that are specific to the SAP HANA database in a system that is not running on HANA.
  Cause:
  
  Database Compatibility: CDS views are designed to leverage the capabilities of the HANA database. If you are working in a non-HANA environment (like an ABAP application server with a different database), the system will not support certain features of CDS views.
  External View Definition: The error specifically mentions that the object is an external view, which means it is intended to be used in a HANA context. This can happen if the view is defined with certain annotations or SQL syntax that is only valid in HANA.
  
  Solution:
  
  Check Database Type: Ensure that you are working in a HANA database environment. If you are not, you will need to either switch to a HANA database or avoid using HANA-specific features in your CDS views.
  Modify the CDS View: If you need to maintain compatibility with a non-HANA database, you may need to modify the CDS view to remove HANA-specific features or annotations. This may involve:
  
  Avoiding the use of certain SQL constructs that are not supported outside of HANA.
  Using standard ABAP views or database views that are compatible with your current database.
  
  
  Use Alternative Approaches: If you need to work with data in a non-HANA environment, consider using traditional ABAP programming techniques or other types of views that are supported by your database.
