How To Fix RT259 - &1 &3 > &2 &3 Network runtime exceeds threshold (&4 dialog steps)

SAP Error Message - Details

• Message type: E = Error

• Message class: RT - Monitoring infrastructure MSG and alert texts

• Message number: 259

• Message text: &1 &3 > &2 &3 Network runtime exceeds threshold (&4 dialog steps)

What causes this issue?

Average frontend network time per dialog step.
During a dialog step, there can be several communication steps between
the SAP server and the local frontend.
The frontend network time is the time that is used in the network for
the first data transfer from the frontend to the SAP server, and the
last data transfer from the SAP server to the frontend (in milliseconds)
during a dialog step.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message RT259 - &1 &3 > &2 &3 Network runtime exceeds threshold (&4 dialog steps) ?

  The SAP error message RT259 indicates that the network runtime for a particular transaction has exceeded a predefined threshold. This can happen in scenarios where the communication between the SAP application server and the database or between different application servers is slow or inefficient. The message typically includes parameters that provide additional context, such as the transaction code, the user, and the number of dialog steps involved.
  Cause:
  
  Network Latency: High latency in the network can lead to delays in data transmission between the SAP application server and the database or between different servers.
  Database Performance: If the database is slow in processing requests, it can contribute to longer network runtimes.
  Heavy Load: A high number of concurrent users or transactions can overload the system, causing delays.
  Inefficient Code: Poorly optimized ABAP code or inefficient queries can lead to longer processing times.
  Configuration Issues: Incorrect settings in the SAP system or network configuration can also lead to performance issues.
  
  Solution:
  
  Analyze Network Performance: Use network monitoring tools to check for latency and bandwidth issues. Ensure that the network infrastructure is robust and optimized.
  Database Tuning: Check the performance of the database. Optimize queries, create appropriate indexes, and ensure that the database is not overloaded.
  Review System Load: Monitor the system load and user activity. If the system is consistently under heavy load, consider scaling up resources or load balancing.
  Optimize ABAP Code: Review and optimize any custom ABAP code that may be causing delays. Use transaction ST05 (SQL Trace) to identify slow-running queries.
  Adjust Thresholds: If the threshold is set too low for your environment, consider adjusting it in the SAP system configuration. This should be done cautiously and with proper justification.
  Check SAP Notes: Look for any relevant SAP Notes that may address known issues related to this error message.
  
  Related Information:
  
  Transaction Codes: Use transaction codes like ST22 (Dump Analysis), SM21 (System Log), and ST03N (Workload Analysis) to gather more information about system performance and errors.
  SAP Support: If the issue persists, consider reaching out to SAP Support for assistance. Provide them with detailed logs and system performance metrics.
  Documentation: Refer to SAP documentation for best practices on performance tuning and network optimization.
  
  By addressing the underlying causes and implementing the suggested solutions, you can mitigate the occurrence of the RT259 error and improve overall system performance.
