• What is the cause and solution for SAP error message SOI1485 - No more tables with open DML/DDL operations (classified with K/C/L) exist ?

  The SAP error message SOI1485, which states "No more tables with open DML/DDL operations (classified with K/C/L) exist," typically occurs in the context of database operations, particularly when dealing with Data Manipulation Language (DML) or Data Definition Language (DDL) operations. This error indicates that the system has exhausted the available tables that can be used for these operations, which can happen in various scenarios, such as during data processing or when executing certain transactions.
  Causes:
  
  Exhaustion of Available Tables: The system has run out of tables that can be used for DML/DDL operations. This can happen if there are too many open transactions or if the system is configured with a limited number of tables for these operations.
  Long-Running Transactions: If there are long-running transactions that hold locks on tables, it can prevent new DML/DDL operations from being initiated.
  Configuration Issues: There may be configuration settings in the database or SAP system that limit the number of concurrent DML/DDL operations.
  Database Locking Issues: Locks held by other processes can lead to this error, especially if they are not released in a timely manner.
  
  Solutions:
  
  Check Active Transactions: Use transaction codes like SM12 (for lock entries) and SM21 (for system logs) to identify any long-running transactions or locks that may be causing the issue. If you find any unnecessary locks, consider releasing them.
  Optimize DML/DDL Operations: Review the DML/DDL operations being performed. If possible, optimize them to reduce the time they take to complete, thus freeing up tables more quickly.
  Increase Configuration Limits: If the system is configured with a low limit for concurrent DML/DDL operations, consider increasing this limit. This may involve adjusting database parameters or SAP settings.
  Database Maintenance: Perform regular database maintenance to ensure that the database is running optimally. This includes checking for fragmentation, updating statistics, and ensuring that there are no underlying issues with the database.
  Restart the Application Server: In some cases, restarting the application server can help clear up any lingering issues that may be causing the error.
  
  Related Information:
  
  SAP Notes: Check SAP Notes related to this error message for any specific patches or updates that may address the issue.
  Database Documentation: Review the documentation for the specific database being used (e.g., HANA, Oracle, SQL Server) for any known issues or configuration settings that may impact DML/DDL operations.
  System Monitoring: Implement monitoring tools to keep track of database performance and transaction locks, which can help prevent this error from occurring in the future.
  
  If the issue persists after trying the above solutions, it may be beneficial to consult with SAP support or your database administrator for further assistance.
