On-Prem to HCI/CPI Integration Issue

Hello Friends,

I am setting up a scenario where I will sending some IDocs to HCI from my ECC system.

I got stuck in the first few steps it self. My RFC connection test fails with below log in SMICM.

[Thr 140695532963584] *** ERROR => NiBufIConnect: non-buffered connect pending after 5000ms (hdl 88;XXXXX-iflmap.hcisbp.eu1.hana.ond
[Thr 140695532963584] *** WARNING => Connect to failed: NIECONN_REFUSED(-10) {00012690
[Thr 140695532963584] IcmConnConnect: Connect failed for session GUI T23_U27624_M0, 100, USER522, HOSTXXXXX, time=12:11:10,

Can you please help in this. I have followed the steps mentioned by Bhavesh.

    Dear Amitabh,

    This error suggests a security/certificate issue with the connection.

    I would recommend the following SAP blog: Cloud Integration – How to Setup Secure HTTP Inbound Connection with Client Certificates :

    I hope this helps.

      Hello Andy,

      I have got a few queries and request for your clarification please.

      - The credential-user mapping certificate should be the one created while we create the SSL Standard PSE in STRUST?

      - Is it mandatory to get this certificate signed by a CA authority? Because even after uploading this certificate in CPI, I am still getting the same error.

      - Just for testing a scenario customers might not want get this signing done. What is an alternative to that?

    Dear Amitabh,

    For certificate authentication it is mandatory to have a certificate signed by an Authority recognised by the Load Balancer of CP, see Load Balancer Root Certificates Supported by SAP:

    Question 6 in KBA ##2524719 - FAQ: SCI/HCI simple questions, provides a number of links for certificate issues with CPI.

    These should be of use for you.

    Kind Regards,
