How to pass non key parameter into GET_ENTITY_SET method

Hi Experts,

I want to pass key field value into GET_ENTITY_SET method as well as non key field value. The key value can be available in lt_key_tab.n Like that where I can get the value or which import parameter hold the non key value in this method, in DPC EXT class?

In that case, what would be possible URI ? How I can pass those non key values in URI which will hit GET HTTP method for GET_ENTITY_SET method when I will test in SAP NETWEAVER GATEWAY CLIENT?

Thanks in advanced,

Regards,
