SAP HANA Graph Engine

Hi All,

      I have been working on SAP HANA Graphs in SPS09.

I have a few doubts.

1. In SPS08,

    We had two table Associations and Infoitems.

          In SPS09 we have Edges and Vertices, I want to know why is that even when i define a term as a vertex it is being created in Edges as well.

This didn't happen in SPS08.

2. I am trying Backward graph traversal and it is not working neither i am getting any error.

     Here is the code

                         CALL GEM('USE WORKSPACE uri:SFPWS;

                                              $successfactors = {uri:successfactors};

                                              $acquiredBy = $successfactors<-[@core:type = uri:acquires]-;

                                               RESULT uri:acquiredBy FROM $acquiredBy;

                                             ');

      The output that has to be is

     The output I am getting is

Thanks and Regards,
