How To Fix RT148 - &1 &3 > &2 &3 monitoring time exceeds threshold value (&4 dialog steps)

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 148

• Message text: &1 &3 > &2 &3 monitoring time exceeds threshold value (&4 dialog steps)

What causes this issue?

The time that is required during the dialog process for the monitoring
itself is too high.

How to fix this error?

Check if the threshold value is set to too low a value - even a value
of around one percent of the dialog response time (Monitoring attribute
<ZH>R3DialogResponseTime</>) does not slow down the response behavior
of the system to a noticeable degree).
If this is not the case, check the Monitoring System in monitor
<LS>CCMS Selfmonitoring</>, which you can find in the monitor set
<LS>SAP CCMS Technical Expert Monitors</>.

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 RT148 - &1 &3 > &2 &3 monitoring time exceeds threshold value (&4 dialog steps) ?

  The SAP error message RT148 indicates that a certain monitoring time has exceeded a predefined threshold value during the execution of a transaction. This typically relates to performance issues in the SAP system, where a specific transaction or process is taking longer than expected to complete.
  Cause:
  
  Long-running Transactions: The transaction or process is taking too long to execute, which could be due to inefficient coding, large data volumes, or complex calculations.
  System Performance Issues: High system load, insufficient resources (CPU, memory, I/O), or contention for database locks can lead to delays.
  Network Latency: If the SAP system is accessed over a network, latency can contribute to longer response times.
  Configuration Issues: The threshold values for monitoring might be set too low for the expected performance of the system.
  
  Solution:
  
  Analyze the Transaction: Use transaction codes like ST22 (Dump Analysis), SM21 (System Log), and ST03N (Workload Analysis) to identify the root cause of the delay.
  Performance Tuning: Optimize the code of the transaction, if applicable. This may involve rewriting inefficient queries, reducing data volume, or improving algorithm efficiency.
  System Resources: Check the system's performance metrics. If the system is under heavy load, consider scaling up resources or optimizing existing workloads.
  Adjust Threshold Values: If the current threshold values are too strict for the expected performance, consider adjusting them in the relevant configuration settings.
  Database Optimization: Ensure that the database is properly indexed and that statistics are up to date. This can significantly improve query performance.
  Network Optimization: If network latency is an issue, consider optimizing the network path or increasing bandwidth.
  
  Related Information:
  
  Monitoring Tools: Use SAP's monitoring tools (like Solution Manager) to keep track of system performance and identify bottlenecks.
  SAP Notes: Check SAP Notes for any known issues or patches related to the specific transaction or error message.
  Documentation: Review SAP documentation for best practices on performance tuning and monitoring.
  
  By addressing the underlying causes and implementing the suggested solutions, you can mitigate the occurrence of the RT148 error and improve the overall performance of your SAP system.
