Connectivity Issue with Third Party


Hi Experts,

I am trying to establish the connectivity with third party and SAP PO.

Steps performed by me -

1) Certificate provided by Partner uploaded in TrustedCA in NWA.

2) Key and certificate generated in SAP PO and shared the certificate with Partner

3) Partner uploaded our certificate in there system

Message from Partner is successfully triggered to our SAP PO Dev system, but it is failing in sender channel.Error is mentioned below -

Error in AS2 Message Signature validation: iaik.cms.CertificateNotFoundException: Certificate for verifying the signature not found

Solution Tried


But, changing the properties and restart of system didn't worked. Same error again.

2) 2227499 - Signature verification failure in SAP AS2 sender adapter

This note says that we need to apply the latest patch SP04 patch 13, but we are currently on SP04 patch 09.

But, in our Sandbox system we are at SP04 patch 08. Still everything is working fine. So, I am not sure if this is a solution.

Please suggest why it is not working in Dev but working in Sandbox?
