SAP Note 28295 - SAPcomm: Faxes not sent from MM, SD...

Symptom:

Fax messages, which are generated in applications MM, SD, etc. are picked up by the SAPcomm communications server, but are not sent.
(The status in the overview of the spool requests does changes from "Waiting / Waiting for output preparation" to "Waiting / Sending to host spooler", but not to "Finished" or "Error".
Fax messages which are, for example, sent from SAPoffice arrive correctly, and the status in the spool changes to "Finished".

Cause and prerequisites

In the application or in the Message Control the standard setting for fax messages is set to the low priority "Send at night rate".
If, however, no editing time point is entered in the SAPcomm configuration for messages with this priority, SAPcomm never passes these on to the fax system. The messages remain in the form of 2 files, *.ctn and *.dtn, in a SAPcomm directory of the fax component (for example, /usr/sap/com/top/data/tf01).

Solution
a) Use a higher priority when generating the messages in the application ("Immediate" or "Next selection time").
b) Enter a processing time for night dispatch in the SAPcomm configuration file. Example: Insert the lines marked below with **** into the file sapcomm.cfg. ...
