Thanks for all your replies.
To reconfirm once again our landscape has following servers.
2 ECC Dev Servers -- 1 for actual development & another for testing. (ECC DEV TEST)
in similar for Quality
2 ECC QA servers -- 1 referring to actual quality & another for UAT (ECC QA TEST)
But there is only one PI DEV server which connects both ECC DEV & ECC DEV TEST
in similar PI QA server will connect to both ECC QA & ECC QA TEST.
Now I have changed the configurations in ICO which is pointing to ECC QA to ECC QA TEST.
I have done the below configurations for that:
1. Run RZ70, this included technical system in my SLD landscape and I have created a business system ECC_QATEST
2. Imported this ECC_QATEST in quality integration builder directly
3. Created SOAP communication channel where the URL is pointing to new ECC QA TEST
4. In ECC QA TEST created a new user PIAPPL_QATEST and that user is configured in SOAP receiver adapter
5. RFC Destination (SM59) of type H is created in ECC QATEST which is pointing to PI QA server
Then I touched ICO configurations directly in PI-Quality system.
In receiver tab I have changed the target system to ECC-QATEST and new SOAP comm channel created is assigned in ICO configurations.
6. Activated the ICO configurations in PI Integration directory (PI QA server)
While dropping the file I could see messages processed but going to old ECC QA system, its not poining to new server.
Thanks,
