• What is the cause and solution for SAP error message SDDIC_ADT_DDLX906 - Quoted identifiers are not supported ?

  The SAP error message SDDIC_ADT_DDLX906 with the description "Quoted identifiers are not supported" typically occurs in the context of using the ABAP Development Tools (ADT) or when working with database objects in SAP HANA. This error indicates that the SQL statement or DDL (Data Definition Language) command you are trying to execute contains quoted identifiers, which are not supported in the context you are working in.
  Cause:
  
  Quoted Identifiers: The error arises when you use double quotes (") around identifiers (like table names, column names, etc.) in your SQL statements. In many SQL dialects, including SAP HANA, quoted identifiers are not allowed or are treated differently than unquoted identifiers.
  Database Compatibility: The SQL syntax you are using may not be compatible with the database system you are working with. For example, some databases allow quoted identifiers while others do not.
  
  Solution:
  
  
  Remove Quotation Marks: Check your SQL statements or DDL commands and remove any double quotes around identifiers. For example, change:
  SELECT "column_name" FROM "table_name";
  to:
  SELECT column_name FROM table_name;
  
  
  Use Backticks for HANA: If you need to use special characters or reserved keywords as identifiers, consider using backticks (`) instead of double quotes, as HANA supports backticks for this purpose.
  
  
  Check Naming Conventions: Ensure that your identifiers follow the naming conventions of the database you are working with. Avoid using reserved keywords or special characters unless necessary.
  
  
  Review Documentation: Consult the SAP HANA SQL and System Views Reference or the relevant documentation for the specific version of SAP you are using to understand the rules regarding identifiers.
  
  
  Related Information:
  
  SAP HANA SQL Reference: This documentation provides detailed information about SQL syntax, including how to handle identifiers.
  ABAP Development Tools (ADT): If you are using ADT, ensure that your development environment is set up correctly and that you are using the appropriate version compatible with your SAP system.
  Community Forums: If you continue to face issues, consider reaching out to SAP Community forums or support channels for assistance from other developers who may have encountered similar issues.
  
  By following these steps, you should be able to resolve the error and successfully execute your SQL statements or DDL commands.
