Hi Naveen,
As per the screenshot you have attached i can see that ECC host entry is missing in the portal server so maintain those entry in portal and viceversa.
-->Did you implemented the SSO properly??? if you are implementing SSO using logon tickets please follow below blog
--> Check the Jco connection which is created for connecting to ECC system.
Also as @Jwala said the System alias should be SAP_ECC_HumanResources , you can keep system object name anything but system alias should be SAP_ECC_HumanResources.
Please let me know if you need any help.
Thanks
Anil kumar
