To use the IGS from an SAP system, some configuration needs to be done on SAP system as well as on IGS side.
On SAP system side, you must:
● in case of ABAP, maintain an RFC destination in the SAP system so that the SAP system can access the IGS.
● in case of Web Dynpro Java, maintain the URL of the IGS.
On IGS side, you need to:
● configure the RFC or HTTP listener so that the IGS is prepared for incoming requests.
You find detailed configuration information under the following link:
