This error is related to the inability to execute an EXPLAIN command for a prepared or reopened SELECT statement.
  Cause:
  
  Database Compatibility: The database you are using may not support the EXPLAIN command for prepared statements or reopened SELECT statements. Different databases have different capabilities and syntax.
  SQL Syntax Issues: There may be issues with the SQL syntax in the prepared statement that prevent the EXPLAIN command from being executed.
  Database Configuration: The database configuration might not allow for the execution of EXPLAIN commands, or the user may not have the necessary permissions.
  SAP Version: The version of SAP or the database connector being used may not fully support the features required for the EXPLAIN command.
  
  Solution:
  
  Check Database Compatibility: Ensure that the database you are using supports the EXPLAIN command for prepared statements. Refer to the database documentation for details.
  Review SQL Syntax: Double-check the SQL syntax of the prepared statement to ensure it is correct and adheres to the database's requirements.

  Consult Documentation: Refer to the SAP documentation and the database documentation for any specific instructions or limitations regarding the use of EXPLAIN with prepared statements.
  
  Related Information:

  Prepared Statements: Prepared statements are precompiled SQL statements that can be executed multiple times with different parameters. They are often used for performance optimization and security (to prevent SQL injection).
  Database-Specific Behavior: Different databases (e.g., Oracle, SQL Server, MySQL, PostgreSQL) have different implementations and support for SQL commands, including EXPLAIN. Always refer to the specific database documentation for accurate information.
