Facing lot of problems with the DATA object -- Urgent

Hi,

I am facing lot of problems with the data object in VC.

1. I created the RFC initially and then imported the data object in to VC. Later i did some modifications to RFC Function module,and when i reload the data object, I am not able to see the new changes done to RFC in VC.

2. Even if i delete the function module, after redeploying the IVIew, results are getting displayed.

3. How stable is the VC?

I restarted the sql server and portal connection to R3 is also made afresh.... still i am viewing such surprise results..

please let me know what might be the problem.
