Symptoms
K2 Connect is throwing error that it can't connect to port 3300. That's because the SAP Server was customized to use port 3206.
Diagnoses
The default gateway port of SAP Server is 3300. That's the default port that K2 Connect will use to connect with SAP Server.
Resolution
We did a quick search on SAP Connection string and found this KB:
http://rfcconnector.com/documentation/kb/0008/
They mention the following:
A typical SAProuter string contains a hostname (/H/) and a port number (/S/), some SAProuter instances are also protected by a password (/W/):
/H/10.0.1.120/S/3201/
e.g.: ASHOST=/H/10.0.1.120/S/3201
We will need to specify the port inside the K2 Connect Destination server configurations following the format of SAP connection strings above.
