1.RFC Connection Error

Q. Not able to Client copy from "000" Client

If someone else has same issue:
1) Create RFC to the to source client,
2) Go to tcode FINB_TR_DEST

3) Input relevant data about RFC.

Run t-code SM59
and create a RFC for client 800.
after that Run t-code MDG_TR_DEST
file the client and RDC destination name here.
and after that u'll try to client copy. - See more at: http://www.saptechies.org/client-copy-error-rfc-destination-mdgtrd01clnt800-error-te/#sthash.YtYAISzr.dpuf
