2252269 - GW: RFC destination (Type T) fails when starting an external program

An RFC destination (Connection Type T: TCP/IP Connection) fails when starting an external program; RETURN CODE: 667.

There can be two different scenarios:

 #Scenario 1:

Same information can be found on the work process trace file (dev_w<x>):

 M  ***LOG R49=> ThCPICSyncWait, CPIC-Error (001667) [thxxcpic.c   3450]
 M  ***LOG R64=> ThCPICSyncWait, CPIC-Error ( CMINIT(SAP)) [thxxcpic.c   3463]
 A  RFC 1234  CONVID CONVID 12345678
 A   * CMRC=1 DATA=0 STATUS=0 SAPRC=667 ThSAPOCMINIT
 A  RFC> ABAP Programm: xxxxxxxx (Transaction: SM59)
 A  RFC> User: <user name> (Client: <cln>))
 A  RFC> Destination: <RFC_Name> (handle: x…, DtConId:
 A  *** ERROR => RFC ======> CPIC-CALL: 'ThSAPOCMINIT' : cmRc=1 thRc=667
 Program (exec) could not be started

 A  *** ERROR => RFC Error RFCIO_ERROR_SYSERROR in abrfcpic.c : 1732
 CPIC-CALL: 'ThSAPOCMINIT' : cmRc=1 thRc=667
 Program (exec) could not be started
 DEST =<RFC_Name>
 HOST =<target_hostname>
 PROG =<Program ID>

SM59 error can also be:

In this case, work process trace file (dev_w<x>) will show:

 M  ***LOG R49=> ThCPICSyncWait, CPIC-Error (001667) [thxxcpic.c   3424]
 M  ***LOG R64=> ThCPICSyncWait, CPIC-Error ( CMINIT(SAP)) [thxxcpic.c   3437]

SystemLog entry (transaction SM21) that can be seen:
    12:34:56 DIA <nr>                                         R4  9 Communication error, CPIC return code 001, SAP return code 667

   #Scenario 2:

The failing program can be different from rsh:
   Error when opening an RFC connection (CPIC-CALL: 'ThSAPOCMINIT' : cmRc=26 thRc=667)
   ERROR: Start of TP ‘path\<program>.exe’ failed
   LOCATION: SAP-Gateway on <hostname>/ sapgw<nr>
