At top level canvas or with a process group?<BR /><BR />Input and output ports facilitate the movement of FlowFiles between a parent process group and a child process group (where the input and output ports exist). So Input/output ports created within a process group only allow for receiving or sending of FlowFiles from the parent process group.<BR /><BR />The top level of your canvas is actually just another process group (root process group). When you create an input or output port here it becomes a remote input/output port capable of transferring Flowfiles over S2S. You will even see that these root level input/output ports are rendered a little different and have more configuration options.</P><P>Thanks,</P><P>Matt</P> Fri, 20 Apr 2018 20:03:47 GMT MattWho 2018-04-20T20:03:47Z
