• What is the cause and solution for SAP error message DHANA_CDS_MODEL006 - Enable case convertion. ?

  The SAP error message DHANA_CDS_MODEL006: Enable case conversion typically occurs in the context of Core Data Services (CDS) views in SAP HANA. This error indicates that there is an issue with the case sensitivity of the identifiers used in your CDS model. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause
  
  Case Sensitivity: SAP HANA is case-sensitive when it comes to identifiers (like table names, column names, etc.). If your CDS view or the underlying database objects have identifiers that differ only in case, it can lead to this error.
  Inconsistent Naming: If the naming conventions are not followed consistently (e.g., using uppercase in some places and lowercase in others), it can trigger this error.
  CDS Annotations: Certain annotations in your CDS view might require case conversion to be enabled.
  
  Solution
  To resolve the DHANA_CDS_MODEL006 error, you can take the following steps:
  
  
  Check Identifiers: Review the identifiers used in your CDS view and ensure that they are consistently cased. For example, if you have a table named SalesOrder and you refer to it as salesorder in your CDS view, it will cause this error.
  
  
  Enable Case Conversion: If your application logic requires case conversion, you can enable it in your CDS view definition. This can typically be done by adding the following annotation:
  @AbapCatalog.sqlViewName: 'Your_SQL_View_Name'
  @AccessControl.authorizationCheck: #CHECK
  @EndUserText.label: 'Your CDS View'
  @CaseConversion: true
  define view Your_CDS_View as select from Your_Table
  {
      // Your fields here
  }
  
  
  Use Quoted Identifiers: If you need to use mixed-case identifiers, consider using quoted identifiers in your SQL statements. For example, use "SalesOrder" instead of SalesOrder.
  
  
  Check for Updates: Ensure that your SAP system is up to date, as there may be patches or updates that address this issue.
  
  
  Consult Documentation: Refer to the official SAP documentation for Core Data Services and case sensitivity to understand best practices and guidelines.
  
  
  Related Information
  
  SAP HANA Documentation: Review the SAP HANA documentation for more details on case sensitivity and how it affects database objects.
  CDS View Best Practices: Familiarize yourself with best practices for creating CDS views, including naming conventions and annotations.
  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and how they resolved them.
  
  By following these steps, you should be able to resolve the DHANA_CDS_MODEL006 error and ensure that your CDS views function correctly.
