SAP Error Message - Details

• Message type: E = Error

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

• Message number: 460

• Message text: Average time for roundtips during a dialog step

What causes this issue?

This monitoring tree element displays the average time that a work
process spendings waiting for the frontend during the communication
steps between the application server and the frontend. These
communication steps are called rountrips.
The time does not include the time used int he network for the first
data transfer from the frontend to the application server and for the
last data transfer from the application server to the frontend
(<LS>FrontendNetTime</>).

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 RT460 - Average time for roundtips during a dialog step ?

  The SAP error message RT460 indicates that the average time for round trips during a dialog step has exceeded a predefined threshold. This can be a performance issue that affects the responsiveness of the SAP system. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause
  
  Network Latency: High network latency can lead to longer round trip times between the client and the SAP server.
  System Load: If the SAP application server is under heavy load, it may take longer to process requests, leading to increased round trip times.
  Database Performance: Slow database queries or locks can delay the response time of dialog steps.
  Inefficient Code: Poorly optimized ABAP code or inefficient queries can lead to longer processing times.
  Configuration Issues: Incorrect configuration settings in the SAP system can also contribute to performance issues.
  
  Solutions
  
  
  Network Optimization:
  
  Check the network connection between the client and the SAP server.
  Use tools to measure network latency and optimize the network path if necessary.
  
  
  
  System Performance Monitoring:
  
  Monitor the performance of the SAP application server using transaction codes like ST03N (Workload Analysis) and ST06 (Operating System Monitor).
  Identify any bottlenecks and take corrective actions, such as increasing resources or load balancing.
  
  
  
  Database Optimization:
  
  Analyze database performance using transaction DB02 (Database Performance Analysis).
  Optimize slow-running queries and ensure that database statistics are up to date.
  
  
  
  Code Review:
  
  Review ABAP code for efficiency. Use transaction SE30 (Runtime Analysis) to identify performance issues in the code.
  Optimize any identified inefficient code or queries.
  
  
  
  Configuration Review:
  
  Check SAP system configuration settings related to dialog processing and adjust them if necessary.
  Ensure that the system is properly sized for the expected workload.
