How To Fix SAML2058 - SOAP communication at endpoint &1 requires an HTTP destination

SAP Error Message - Details

• Message type: E = Error

• Message class: SAML2 - SAML2 Nachrichten

• Message number: 058

• Message text: SOAP communication at endpoint &1 requires an HTTP destination

What causes this issue?

Because of technical requirements, the endpoint &MSG1& can only use an
HTTP destination.

System Response

SOAP bindings from the system can only be used over HTTPS from HTTP
destinations. The reason lies in the use of the SSL protocol. This
requires a certificate for the binding. Outbound SSL connections can
only go over HTTP destinations for this reason.

How to fix this error?

In transaction SM59 create a destination with the prefix "SAML2_" of
type G (HTTP). For example, SAML2_SOAP. This HTTP destination requires
an SSL configuration, in which the client certificate for the connection
to &MSG1& is saved in the SSL PSE.

Procedure for System Administrators

Use SM59, to create an HTTP destination of type G (HTTP) with the prefix
SAML2_.
