Hi Jannus,
I checked the set up. in of the link its mentioned that in RFC destination we need to add the SAP gateway and service details from PI. Currently in ECC side in RFC destination the sap gateway n service is blank. And in inboundRA properties the localgateway is mentioned as "true'
I tried mentioning the PI gateway and service in RFC destination and triggered IDOC. But it showed error in SM58 as " And IDOC exception has occured"
Thanks,
Tina
