Managing Connection and Communication Timeouts and Retries
If an output request is sent to a remote output device, the SAP System verifies that it can reach this output device.
If the spool work process waits more than 15 seconds for a reply, then it records the problem in the SAP System log. You can therefore check in the system log for devices that have chronic communication problems.
If the spool work process must wait more than 30 seconds, then it locks the output device for five minutes and goes on to other output requests. The output request keeps the status Waiting. At the end of this lock period, the spool work process attempts to establish communication again.
The output requests are only reactivated once the host spool system is available.
The connection test is repeated three times every five minutes. If the remote host spool service cannot be reached, the output requests still have the status Waiting.
The connection test is restarted (three times every five minutes) if
The output requests are reactivated once the host spool system can be reached. This operation can be repeated up to three times. If the output requests could still not be output, they are given the status Error.
You can set timeouts both centrally in the system profile as well as individually in the individual output device definitions.
