Hello experts,
I'm having an unknown error ..i had configured stms successfully and i could also transport requests from dev->qas successfully.But by the time when requests transporting from qas->prod transport request can be released with out error but nothing reaches in import queue ..and my landscape details: dev and qas are in one system and prod in another separate system..while i'm searching i could found an error possible behind the unsuccessful transport that is checking transport groups..
and any ideas experts???!!
