Thanks for suggesitons..!
I understand that SM59 entry for SAP_HCM_PROXY should point to ECC INternal itself or correct me if this Shoudl point from ECC to GW .
We although did tried both ways but nothing work .
Still the same Error 404 in getting response from CHIP
"Also suggest if we have to publish the page pers , cust , conf and UI Launchpad , Quickview on ECC or should this be on GW..
Thanks
