Hi All,

We have completed system copy of  netweaver 7.01 portal server. Our source system is installed on single host but our target system is in distributed environment. Now we have getting error while using portal "JCo destination doesnot exist". while checking from nwa jco destination is showing but not maintained,

While creating destination we are getting below error,

Dear Sriram,

While creating JCo its giving error like "Connection CFC already exists in the SLD. Please choose another name. ".  In target machine it is fetching jco destination from db host instead of ci. While checking in sld technical system it is show both CI and DB. and in CI  JCO destination is present.



Thanks & regards,

Hi Jithin ,

Have you set up the SLD system in data supplier target and sent data from your new system to the SLD ?

You can also verify this using the timestamp of the registered system in SLD.
