Hi Mahesh,
Create RFC destination (TCP/IP) LCRSAPRFC for the SLD connection.
Use TCode SM59 to create RFC Destination in ECC
RFC Destination in ECC : LCRSAPRFC
Connection Type: T
Description: <your description><in our case LCRSAPRFC>
Technical Setting:Under the Technical settings tab page, select radio button Registered server Program
and In the Program ID field under Registered Server Program, enter LCRSAPRFC_PID.
This program ID (LCRSAPRFC_PID) must correspond to the ID specified in the RFC engine settings on the Integration Server host.
Also check the NWA for similar settings.
