• What is the cause and solution for SAP error message CDS_UNIT_MESSAGE102 - Table functions are only supported in HANA. Cannot create double for '&1' ?

  The error message CDS_UNIT_MESSAGE102 in SAP indicates that you are trying to create a Core Data Services (CDS) view or a table function that is not supported in the database system you are using. Specifically, this error occurs when you attempt to use a feature that is only available in SAP HANA, but your system is not running on HANA.
  Cause:
  
  Database Compatibility: The CDS view or table function you are trying to create uses features that are exclusive to SAP HANA. If your system is running on a different database (like Oracle, SQL Server, etc.), you will encounter this error.
  Incorrect Configuration: The system might be misconfigured, leading to the assumption that it can use HANA-specific features when it cannot.
  
  Solution:
  
  Check Database Type: Ensure that your SAP system is running on SAP HANA. You can check this in the system information or by using transaction code DB02 to see the database type.
  Modify the CDS View/Table Function: If you are not on HANA, you will need to modify your CDS view or table function to remove any HANA-specific features. This may involve:
  
  Avoiding the use of certain SQL functions or constructs that are not supported in your database.
  Rewriting the logic to be compatible with the database you are using.
  
  
  Use HANA Features: If you need to use HANA-specific features, consider migrating your database to SAP HANA if feasible and appropriate for your organization.
  Consult Documentation: Refer to the SAP documentation for the specific features you are trying to use to understand their compatibility with different databases.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this issue or provide additional guidance.
  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and what solutions they have found.
  Training and Resources: Consider training on CDS views and HANA-specific features if you are planning to work extensively with SAP HANA.
  
  By following these steps, you should be able to resolve the error and create your CDS views or table functions successfully.
