How To Fix FMCF173 - Maximum runtime for dialog processes can be overwritten

SAP Error Message - Details

• Message type: E = Error

• Message class: FMCF -

• Message number: 173

• Message text: Maximum runtime for dialog processes can be overwritten

What causes this issue?

You have set cascaded parallel processing, that is, the data selection
is divided between several dialog processes. If there are large amounts
of data, the maximum runtime for dialog processes (profile parameter
RDISP/MAX_WPRUN_TIME) can be exceeded and can cause the processes to be
terminated.

System Response

This message can be issued as a warning or as an error depending on the
settings for the profile parameter RDISP/MAX_WPRUN_TIME.

How to fix this error?

Check the value of the profile parameter RDISP/MAX_WPRUN_TIME and change
it if necessary.
We recommend that you set the parameter for the program run to unlimited
(value 0). At the end of the program run, the original value should be
set again.

Procedure for System Administrators

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 FMCF173 - Maximum runtime for dialog processes can be overwritten ?

  The SAP error message FMCF173, which states "Maximum runtime for dialog processes can be overwritten," typically occurs in the context of SAP's dialog processing. This message indicates that the maximum runtime for dialog processes has been exceeded, which can lead to performance issues or timeouts in the system.
  Cause:
  
  Long-Running Dialog Processes: The dialog processes may be taking longer than the configured maximum runtime, which can happen due to complex transactions, heavy data processing, or inefficient coding.
  System Load: High system load or resource contention can lead to longer processing times for dialog tasks.
  Configuration Settings: The default settings for maximum runtime may not be suitable for the current workload or system performance.
  
  Solution:
  
  
  Increase Maximum Runtime:
  
  You can adjust the maximum runtime settings for dialog processes in the SAP system. This can be done by modifying the profile parameters.
  Use transaction RZ10 to change the profile parameters. Look for the parameter rdisp/max_wprun_time and increase its value. This parameter defines the maximum runtime for dialog work processes in seconds.
  
  
  
  Optimize Code:
  
  Review the ABAP code for the transaction or report that is causing the issue. Look for opportunities to optimize the code to reduce execution time.
  Consider breaking down complex processes into smaller, more manageable tasks.
  
  
  
  Monitor System Performance:
  
  Use transaction ST03N to analyze workload and identify long-running transactions.
  Check for any performance bottlenecks in the system using transaction ST04 (database performance) and SM50 (work process overview).
  
  
  
  Review Background Jobs:
  
  If the dialog process is related to background jobs, ensure that they are not consuming excessive resources or conflicting with dialog processes.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional guidance.
  
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for detailed information on dialog process management and performance tuning.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have implemented.
  System Monitoring Tools: Utilize SAP's monitoring tools (like Solution Manager) to keep track of system performance and identify potential issues proactively.
  
  By addressing the root causes and implementing the suggested solutions, you should be able to resolve the FMCF173 error and improve the performance of your SAP system.
