We are in process of implemented FIORI,(a Central HUB installation).
We deployed, 1)Create sales order, 2)Change sales order and 3)tracking sales order Apps.
Everything went smooth, till the Trusted RFC part.
We are facing issues with Trusted RFC. we are able to execute authorization test successfully form SMT1 of ECC to Gateway server, but unable to get successful authorization test form Gateway server to ECC.
We are getting the below error, while testing form SMT1.
we maintained Message server port entries in both systems services file, and also assigned the required Authorization to the RFC user(S_RFCACL)but still some this is fishy in the setup.
