• What is the cause and solution for SAP error message DB6PM193 - Volatile table without statistics must not be scheduled user controlled ?

  The SAP error message DB6PM193 indicates that a volatile table is being scheduled for user-controlled operations without having the necessary statistics. This error typically arises in the context of database operations where the system requires statistical information to optimize query performance.
  Cause:
  
  Volatile Tables: These are temporary tables that exist only for the duration of a session. They do not persist beyond the session and are often used for intermediate calculations or temporary data storage.
  Lack of Statistics: The error suggests that the volatile table does not have the required statistics. Statistics are essential for the database optimizer to make informed decisions about how to execute queries efficiently.
  User-Controlled Scheduling: The error occurs when a user attempts to schedule operations (like queries or data manipulations) on these volatile tables without the necessary statistics being available.
  
  Solution:
  
  Gather Statistics: Ensure that statistics are collected for the volatile table before scheduling user-controlled operations. This can typically be done using database commands or through the SAP interface, depending on the database system in use.
  
  For example, in some databases, you might use commands like ANALYZE TABLE or similar to gather statistics.
  
  
  Avoid User-Controlled Scheduling: If the volatile table is not meant to be scheduled for user-controlled operations, consider using it in a way that does not require such scheduling.
  Check Configuration: Review the configuration settings related to the handling of volatile tables and statistics in your SAP system. Ensure that the system is set up to automatically gather statistics for volatile tables if applicable.
  Consult Documentation: Refer to the SAP documentation or the specific database documentation for more details on handling volatile tables and statistics.
  
  Related Information:
  
  Database Management: Understanding how your specific database (e.g., HANA, Oracle, SQL Server) handles volatile tables and statistics is crucial. Each database may have different commands and best practices.
  Performance Tuning: Regularly gathering statistics and monitoring performance can help prevent such errors and improve overall system efficiency.
  SAP Notes: Check SAP Notes for any specific patches or updates related to this error message, as SAP frequently updates its software to address known issues.
  
  If the problem persists after trying the above solutions, consider reaching out to your database administrator or SAP support for further assistance.
