Thanks Ekansh...
You are correct it’s an HTTP POST method. Due to security reason business don't want to use HTTP GET method as data is visible in URL.
We tried to add custom handler class to SICF node to UI5 application but it is not triggering. System is only triggering below standard handler.
/UI5/CL_UI5_APP_HTTP_HANDLER2
/UI5/CL_LREP_HTTP_HNDLR_700
/UI5/CL_UI5_HTTP_HANDLER2
Still not able to resolve issue,
Thanks & Regards,
Nikhil
