We can provide the hostname/IP address in SLD/Technical Systems and also in Communication channels as well.
Which one is recommended by SAP and which one overrides the other? I know I can do a simple test to find out myself but do not have enough authorizations for various components. Can anyone help me with this question?
Per my understanding creating Technical systems in SLD is to keep the control at one place and away from the developers so that things won't flow to the wrong system if someone mistakenly puts inappropriate hostname (Q for Dev etc).
But I am also hearing that Communication channel can not read from SLD in practice and could lead to some failures. Can anyone throw some light on this?
