Iam using RFC sender in my scenario. I have created an RFC destination in R/3 with the details Program ID, GatewayHost, Service. Maintained the same details in RFC sender communication channel of XI. After activating my communication channel I tested my RFC destination R/3. It was succesful.
But these days we are facing the problem with that. It says ' Program Id not registered'. We used to get this error whenever either of the system(R/3, XI) goes down. that time i used to go n activate my Comm. channel the connection would be established once again.
Please let me know why iam facing this error also let me know the steps to resolve it.
Even I tried michel's blog on sender RFC....
