• Message number: 517

• Message text: No additional fill batch process available (setting for max. no.: &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.
