• Message class: BGRFC - qRFC - New Background RFC

• Message number: 379

• Message text: Configure a sufficient number of dialog work processes (see long text)

What causes this issue?

You have specified a number of schedulers other than zero. To ensure
that schedulers are started on the application servers, at least three
dialog work processes must be configured. For each application server,
the number of configured dialog work processes must be at least two more
than the number of schedulers. If you have specified -1, at least three
dialog work processes must be configured.

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 BGRFC379 - Configure a sufficient number of dialog work processes (see long text) ?

  The SAP error message BGRFC379 indicates that there are not enough dialog work processes available to handle the requests for background RFC (BGRFC) processing. This can lead to performance issues or failures in processing background tasks that rely on RFC communication.
  Cause:
  
  Insufficient Dialog Work Processes: The system does not have enough dialog work processes configured to handle the incoming requests.
  High Load: There may be a high volume of requests being processed, which can exhaust the available dialog work processes.
  Configuration Issues: The SAP system may not be optimally configured for the workload it is handling.
  Long Running Transactions: If there are long-running transactions or processes, they may be holding onto dialog work processes longer than necessary.
  
  Solution:
  
  
  Increase Dialog Work Processes:
  
  Go to the SAP system profile parameters and increase the number of dialog work processes. This can be done in the instance profile (usually found in transaction RZ10).
  Look for the parameter rdisp/wp_no_dia and increase its value. The exact number will depend on your system's capacity and workload.
  
  
  
  Monitor Work Process Usage:
  
  Use transaction SM50 to monitor the current usage of work processes. This can help identify if there are any processes that are stuck or taking too long.
  Check for any long-running jobs or transactions that may be consuming resources.
  
  
  
  Optimize Background Jobs:
  
  Review and optimize background jobs that are scheduled to run. Ensure they are not overlapping or running at the same time unnecessarily.
  Consider staggering the execution of jobs to reduce peak load.
  
  
  
  Check System Performance:
  
  Analyze the overall system performance using transaction ST03N to identify any bottlenecks or performance issues.
  Ensure that the hardware resources (CPU, memory, etc.) are adequate for the workload.
  
  
  
  Review Configuration:
  
  Ensure that the SAP system is configured according to best practices for your specific workload and usage patterns.
  
  
  
  Restart the Instance:
  
  In some cases, restarting the SAP instance can help clear any stuck processes and free up resources.
