SAP Note 19539 - SAPcomm and Topcall: error E1102

Symptom:

Error when sending fax documents. Error message in log file of SAPcomm component "TOP":
E1102 Error sending to Topcall. RC=12.

Cause and prerequisites

The recipient number that Topcall sends to SAPcomm (before sending the document) is different from the original recipient number.
The cause for this may be:
1) The number was changed in Topcall due to specific configuration
for this device.
2) Parameter MASK was set in the SAPcomm configuration file.
As a result, the mask name was added to the recipient number.

Solution
Starting in SAPcomm version V3.0A1, subsequent changes to the recipient number will no longer cause the send transaction to terminate.
Workaround:
1) Change the configuration of the Topcall device in such a way
that the device no longer changes the recipient numbers.
2) Remove the "MASK" parameter from the SAPcomm configuration
file. Instead, refer to the required Topcall mask by adding the
Topcall statement
++INCLUDE
to all the R/3 layout sets you have assigned to documents for
sending via Topcall.
