What causes this issue?

During the process of resetting the availability data before the actual
availability check, an error occurred. It is possible that one of the
selected orders could not be blocked.

System Response

The collective availability check will be terminated after resetting
the data of all selected orders (except for those where errors
appeared). In other words, the actual availability check is not carried
out for any of the selected orders.

How to fix this error?

In the output of the order information system, analyze which order or
orders have value 08 or 09 entered as the 'Result of Availability
Check' (technical field name RETCODE). An error occurred for these
orders, which you can examine more closely in the respective logs for
the collective availability check.
If you have called the collective availability check in the background,
(batch call), then you can determine the order or orders causing the
error, as well as the cause of the error, from the job log.
After the errors have been corrected (or when the orders affected are
not selected for check), the collective availability check can be
started 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.
