  The SAP error message SRT_WSP798 indicates that the PSE (Personal Security Environment) for WSSE (Web Services Security) X.509 certificate has not been configured. This error typically arises when you are trying to use web services that require WSSE security, but the necessary security settings, particularly the X.509 certificate, are not properly set up in the SAP system.
  Cause:
  
  Missing PSE Configuration: The PSE for the WSSE X.509 certificate is not created or configured in the SAP system.
  Incorrect PSE: The PSE might be incorrectly configured or not linked to the appropriate service.
  Transport Layer Security (TLS) Issues: If the system is expected to communicate over HTTPS, the necessary certificates for TLS might not be set up correctly.
  Authorization Issues: The user or service account may not have the necessary permissions to access the PSE.
  
  Solution:
  To resolve the error, follow these steps:
  
  
  Create or Configure the PSE:
  
  Go to transaction STRUST in the SAP GUI.
  In the SSL Client (Anonymous) or SSL Server tab, check if the PSE for WSSE X.509 is present.
  If it is not present, create a new PSE by selecting the appropriate option (e.g., "Create" or "Import").
  If it is present but not configured correctly, you may need to import the correct X.509 certificate.
  
  
  
  Import the X.509 Certificate:
  
  Obtain the X.509 certificate from the relevant certificate authority (CA) or generate a self-signed certificate.
  In the STRUST transaction, select the PSE and use the "Import" function to add the certificate.
  
  
  
  Check the Service Configuration:
  
  Ensure that the web service you are trying to call is configured to use the correct PSE.
  Check the service definition in transaction SOAMANAGER to ensure that the correct security settings are applied.
  
  
  
  Test the Configuration:
  
  After configuring the PSE, test the web service call again to see if the error persists.
  You can use tools like SOAP UI or Postman to test the web service independently.
  
  
  
  Check Authorizations:
  
  Ensure that the user or service account has the necessary authorizations to access the PSE and perform the required operations.
