[juanpablo_velazquez]

Hi Experts.

I need change a RFC connection, but when I try enter to Visual Administrator > server> services-->JCo RFC Provider

this message is sent "Error while loading service JCo RFC Provider".

I searched the error in the log visual_administration.0.trc, and this is the text

HI,

I would say open OSS msgs for SAP. They can help further.

Thanks,

The problem was solved, some components like EP_BUILDT, SAP_BUILDT, SAP_JTECHS, SAP-JEE were "marked"

under NWDI control, and we did deploy again

thanks

I tested the connection from BW system in the SM59 transaction and the result was succesfully. = S

[juanpablo_velazquez]

Yes I do, I have a RFC Listener with BW and ECC 6.0, I want change the client connection to ECC.

Hi,

do you have any backend conectivity or RFC setup with any other systems?

Thanks,

I restart the service and the instance too, but when I click to start then show me the error message "Error while loading service JCo RFC Provider".

Hi,

I think it looks like Jco services are not running. Please login to visual admin,>.services>> jco*, stop and start the services. Retry your configuration.

Thanks,
