I am intend to create trust between XS engine and SAP gateway. When I log in HANA XS admin, open trust manager and create a trust store, I cannot create a certificate request according to the HANA platform admin guide chapter 15.3 (http://help.sap.com/hana/SAP_HANA_Administration_Guide_en.pdf) because there is no such creation icon on my screen, as shown in the screenshot below. Another icon "put cert reponse" is also missing from the screen.
however, according the SAP standard admin guide, there should be such icons exist there, see the screenshot from admin document below.
Without these two icons, steps about the trust relationship creation cannot be executed. I am using HANA SYSTEM user, which contains all required authorizations. I am not sure what happen here, could you please kindly help?
