SSO issue with different R/3 system in SAP Portal

Hello Experts,

I want to show FIORI Launchpad and HANA Launchpad in portal.

I created two system landscape 1) ECC6_FIORI for fiori launchpad 2)ECC6_HANA for hana launchpad.

Both system uses different SID and client. for example: ECC6_FIORI use SID= ABC,client=1 and ECC6_HANA uses SID=xyz,client=2

we are using same web dispatcher for both the system to display launchpad in portal.

FIORI launchpad is display proper .But problem is when i click on hana launchpad iview ,it shows me pop-up window "Authentication required"and username and password for ABC/2 (ABC is a SID of ECC6_FIORI and 2 is client of ECC6_HANA).

i don't understand why this happen.

I done SSO related config in NWA like, generate trusted system for both system and export certificate from SAPLogonTicketKeyPair-Cert and import in STRUSTSSO2.

System Test Result:

1) ECC6_FIORI : All test connection are correct. (Working properly in portal)

2) ECC6_HANA : Test connection done from system landscape overview, gives an error mention below.

                                   No Connection to System: ECC6_HANA found.

                                   com.sapportals.connector.connection.ConnectionFailedException:

                                   Connection Failed: A Nested Exception Occurred.Could not initialize physical connection.

                                   Connection Failed:A nested exception occured:could not create JCO connection.

                                       Name or password is incorrect (repeat logon).

Thanks,
