Urgent:Idoc stuck with status 03 in TRFC

My Idoc is in status 03, but it is not reached to destination.

I guess It is stuck in Rfc layer or in some QUEUE.

There was quality system refresh last week here with Production system.

Pelase suggest what seetings need to be changed and where.

in SM58 it give the following error

'RFC address XXXXXXX doesn't exist'

(where XXXXXXX i m not mentioning here for Client security reasons)

is there any program to clear these layers?

Thanks a ton in advance 😊 and the answer will be adequately awarded.
