You need to remove the old generated files(certreq, cred_v2, local.pse, srcert) from previous certificate request. To do this you can either rename these files or create a new folder and move these files into it.2. Login to http://service.sap.com/saprouter-sncadd and click the Apply now button. From the list of SAProuters registered to your installation, choose the relevant Distinguished Name.3. Generate the certificate Request. To do this go to your SAProuter server and run this command on the saprouter directory.sapgenpse get_pse -v -r certreq -p local.pse Example: sapgenpse get_pse -v -r certreq -p local.pse CN=example, OU=0000123456, OU=SAProuter, O=SAP, C=DEYou will be asked twice for a PIN here. Please choose a PIN and document it, you have to enter it identically both times. Then you will have to enter the same PIN every time you want to use this PSE.4. Display the output file certreq and with copy&paste (including the BEGIN and END statement) insert the certificate request into the text area of the same form on the SAP Service Marketplace from which you copied the Distinguished Name.5. In response you will receive the certificate signed by the CA in the Service Marketplace. Copy&paste the text to a new local file named srcert, which must be created in the same directory as the sapgenpse executable.6. With this in turn you can install the certificate in your saprouter by calling: sapgenpse import_own_cert -c srcert -p local.pse7. Now you will have to create the credentials for the SAProuter with the same program (if you omit -O , the credentials are created for the logged in user account).sapgenpse seclogin -p local.pse -O Note: The account of the service user should always be entered in full 8. This will create a file called cred_v2 in the same directory as local.pse9. To check if the certificate has been imported successfully, run the following command: sapgenpse get_my_name -v -n IssuerThe name of the Issuer should be: CN=SAProuter CA, OU=SAProuter, O=SAP, C=DE
