Hi Muhammad
can you publish also config STRUSTSSO2 in client 000 and 220? Did you give the S_RFC authorisations to the user? Do you see any error in sm21 of the backend?
Last chance could be go to SM50, select all the processess then from menu process option trace and select active components. Change the trace level to 3 and select only the security option.
Repeat the check from the portal then go to sm50 again and check in trace files of the processess what is the error that appear
Let me know how it goes
