How To Fix TRUST013 - Certificate no longer has signature (use restriction)

SAP Error Message - Details

• Message type: E = Error

• Message class: TRUST - Certificate Management

• Message number: 013

• Message text: Certificate no longer has signature (use restriction)

What causes this issue?

Certificates entered in the certificate list of a PSE no longer have a
signature and can therefore only be used for verifying digital
signatures. The certificate itself can no longer be verified.
The certificate you want to export comes from the certificate list of
the PSE and its use is therefore restricted (as described above).

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Note that the exported certificate is only suitable for import into a
certificate list of a PSE.
