Hi Azhar,
Thanks for reply. I checked all the RFC connections, they work fine.
Just to add, I could see that I have problem with "Integration Server (ABAP Cache)".
Shot Desciption: Errr when notifying cache receiver
Comprehensive Description:
Unable to notify Integration Server affected by data changes
HTTP connection to http://piqa:50000/sap/xi/cache?sap-client=200 returns status code '401' (Unauthorized) in response
Thank you.
