How To Fix BT518 - Unable to find date in calendar. (Is the calendar correct?)

SAP Error Message - Details

• Message type: E = Error

• Message class: BT - Background processing messages

• Message number: 518

• Message text: Unable to find date in calendar. (Is the calendar correct?)

What causes this issue?

A periodic job was terminated because it could not schedule a new date
in its factory calendar. The calendar is assigned to the job during
scheduling.
Possible causes of the problem:
RESET N1
The calendar does not contain any days (workdays) that allow the job to
be executed. The calendar is probably not correctly defined.
Example: The calendar does not contain any workdays (it only consists
of non-workdays).
This might then be the cause if the job was scheduled with the options
'on workdays only' and 'omit job'.
A periodic job, which is scheduled for a particular workday in the
month (e.g. 3rd workday), cannot find a date in the current calendar.
This is another case in which the calendar is probably not correctly
defined.
Example: The calendar ends with the end of the current year, and the
periodic job is next due to start in the next year.
The factory calendar could not be found or could not be loaded. Check
whether the calendar is defined.
If the calendar does exist, you should check whether the calendar
buffer is large enough or whether there are other storage space
problems.
For more information on the calendar buffer, refer to the documentation
for profile parameters <LS>zcsa/calendar_ids</> and
<LS>zcsa/calendar_area</> in the profile maintenance function and in
the Customizing system (Customizing IMG, <LS>Basis</> section).

System Response

The scheduler flags this job as terminated. No job step in this job was
executed.
The job chain to which this job belongs is also terminated. Automatic
scheduling of this job is not continued.
This message, along with other messages, are entered in the log of this
job in order to point out this problem. Additional messages should
indicate why scheduling failed.
Previous runs of this job are not affected by this termination, but the
job cannot be scheduled periodically until the problem with the
calendar has been eliminated.
For consistency reasons, the system also displays a date and time for
this job in the job log. These are values for the scheduling period and
not the execution time. It is the time when the system determined that
the new job cannot run.
Caution:
The time is almost identical to the date of the last periodic job in
the chain to be correctly processed.
It is possible that this predecessor is not yet finished but is still
active.

How to fix this error?

Check whether the calendar (calendar ID) still exists, whether its
values are correct and whether the start restriction for your job is
correctly set.
Perhaps your calendar is simply too short.
When you have solved the problem with the calendar (or eliminated the
cause, if different), you must reschedule the periodic job so that it
can be automatically scheduled again after your period entries. The
background processing system cannot recommence periodic scheduling on
its own.
To reschedule the job, select menu options <LS>Tools</> ->
<LS>Administration</> -> <LS>Jobs</> -> <LS>Job overview</>. Display
the job in the overview and then select <LS>Job</> -> <LS>Scheduling</>
-> <LS>Repeat</>.
