File to Proxy scenario message failed in ECC with staus SYSFAIL
We are working on File to proxy scenario, PI able to send message successfully to ECC, but In ECC , message got stuck in queues with the status 'SYSFAIL',
when I read the error message it is showing Address Invalid.
when I run the LUW, it is giving 'Function module does not exist or EXCEPTION 'raised message.
I'm using PI 7.1 EHP1 , ECC 6.0, can anyone suggest the trouble shooting guidelines for this issue?
