Error using Component in another DC

28 Views

Hello Everybody,

I have developed one DC in which I have created one RFC model and I have written all the methods related to it.

Now, I am using this DC in another DC and calling methods to call those RFC models.

This application was working perfectly fine. But, after the changes in structure of RFC and re-importing RFC model, I got following error in my DC in which i am using RFC DC.

I have sync my sources and also sync used dcs for RFC DC.

I have deployed this RFC dc on server. I have restarted my server also. But, still it is giving this problem.

What should be the reason behind this?

Thanks in Advance,
