• What is the cause and solution for SAP error message DD_MT_SHARING028 - Shared tables are only supported on HANA ?

  The SAP error message DD_MT_SHARING028 indicates that shared tables are only supported on the SAP HANA database. This error typically arises when you attempt to use shared table features in a database environment that does not support them, such as traditional databases like Oracle, SQL Server, or others.
  Cause:
  The primary cause of this error is the attempt to create or use shared tables in a non-HANA database environment.

  Solution:
  To resolve this error, you have a few options:
  
  
  Switch to SAP HANA: If your project or application requires the use of shared tables, consider migrating your database to SAP HANA. This would allow you to utilize the shared table functionality without encountering this error.
  
  
  Avoid Shared Tables: If migrating to HANA is not feasible, you may need to redesign your database schema to avoid the use of shared tables. This could involve creating separate tables for each schema or using other methods to achieve the desired functionality without shared tables.
  
  
  Check Configuration: Ensure that your system configuration is set up correctly and that you are not inadvertently trying to use shared tables in a non-HANA environment.
  
  
  Related Information:
  
  SAP HANA Documentation: Review the official SAP HANA documentation for detailed information on shared tables and their usage.
