Keystoreentry not found in soap receiver channel

Hello experts!

I am developing an interface RFC --> SOAP

This SOAP call is for an third party web service and my basis team set up a certificate into visual admin in order to be able to communicate with the web service.

problem is when i am trying to configure client certificate authentication in soap receiver channel, i am unable to find the certificate in the key store Entry list.

Can any one tell me what might be the issue?

Regards,
