A precondition for using the IGS from an SAP system is that the SAP system knows the IGS. To achieve this an RFC destination must be maintained both in the SAP system and also in the IGS so that the SAP system can access the IGS.
? Only one IGS Multiplexer is to be installed.
? The number of IGS Portwatchers should not be more than double the number of CPUs of the machine.
? The interpreters should be sensibly distributed.
To maintain the RFC destination in the SAP system, read note 454042.
