Ask about function import is redefines from BOPF

Hi Experts,

I am new with BOPF and  function imports in gateway. I am facing with a problem about the create service for EHSM4.0

I am create a odata service from SAP gateway with tcode segw.

I redefined from BOPF service with Business Object is EHHSS_INCIDENT, default query is SELECT_ALL.

I imported all actions of this BO,

The my issue is : I can not run any function import with URL because I always see Function Import parameter is ENTITY_NAME and NODEID like this:

I don't know what value have to input for this function, what is NODE_ID,

Who can help me on this? How can I run this URI?

Thanks you for your help

Best regards
