Preparing the WS Consumer AS ABAP for Issuing
the Signature
You can use the following procedure to set up the consumer system so that it can sign its requests to the provider system.
● You know which signature certificate is to be used for the consumer system and know which keystore (PSE) it is stored in.
...
1. In the consumer system, set the option to use signatures and encryption (for example, in the SOA Manager, under Business Administration → Web Service Administration → Signature & Encryption (Asymmetic Binding), the option Signature & Encryption (Asymmetric Binding)).

If you specify the WSDL URL when creating the logical port of the consumer system, the WSDL automatically sets this option.
