• Message class: CNV_10020 - Message class for package 10020

• Message number: 515

• Message text: No additional batch process is available (setting for max. number: &2)

What causes this issue?

The system could not start a job - either because no additional batch
job is available or because the maximum number of batch processes (&V2&
) that has been preset for the package &V1& is already running.

How to fix this error?

If you still want to start more jobs and you have free batch jobs
available, increase the maximum number of batch processes accordingly.
&HINTS&

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

<zh>The number of batch processes is determined at cross-server level.
</>
Using the parameter JOB_START_MODE_FILL_LOR (transaction
CNV_10020_PARAM), you can set the number of batch processes for CNV
jobs, fill jobs or total number of jobs. (The term 'fill jobs' refers
to all jobs that access object tables, such as jobs for creating
intervals or jobs for deleting the object tables.)
If the org. package runs without the interface package, you can control
the maximum number of batch processes using the parameter
MAXIMUM_NUMBER_OF_BATCH_PROCESSES (transaction CNV_10020_PARAM).
<zh>CWB context:</> You can define the maximum number of batch processes
by setting "Number of work processes running in parallel" in the
conversion runtime parameters accordingly.

• What is the cause and solution for SAP error message CNV_10020515 - No additional batch process is available (setting for max. number: &2) ?

  The SAP error message CNV_10020515 indicates that there are no additional batch processes available for the specified maximum number of processes. This error typically occurs in the context of data migration or conversion processes, particularly when using SAP's tools for data transfer or system conversion.
  Cause:
  
  Max Batch Processes Reached: The system has reached the maximum number of batch processes that can be executed simultaneously. This limit is defined in the configuration settings.
  Configuration Settings: The settings for the maximum number of batch processes may not be configured correctly or may be set too low for the current operation.
  System Resource Limitations: The system may be experiencing resource constraints (e.g., CPU, memory) that prevent additional batch processes from being initiated.
  
  Solution:
  
  
  Increase Max Batch Processes:
  
  Check the configuration settings for the maximum number of batch processes allowed. This can typically be done in the transaction code RZ10 or through the relevant configuration settings in the SAP system.
  Increase the limit for the maximum number of batch processes if necessary. This may involve adjusting parameters such as rdisp/bt_max_no or similar settings depending on your SAP version.
  
  
  
  Monitor and Optimize Resource Usage:
  
  Monitor the system's resource usage to ensure that it can handle additional batch processes. Use transaction codes like SM50 or SM66 to check the status of background jobs and system performance.
  If the system is under heavy load, consider scheduling batch jobs during off-peak hours or optimizing existing jobs to free up resources.
  
  
  
  Check for Stuck or Long-Running Jobs:
  
  Investigate if there are any stuck or long-running background jobs that may be consuming resources. You can use transaction SM37 to review the status of background jobs and terminate any that are not progressing.
