I suppose that my problem is problem of Windows Vista.

Hi Josue

Have it ever worked to reimport the model or have you always got this error trying to reimport a model?

Is it a general problem or only related to this particular model?

What kind of model is it? (Adaptive RFC, Webservice?)

If I examine the stack trace, that you provided, it seems that this has something to do with the SAPLogonHelper class. Can you relate this to something? Does the user you are trying to logon as exist in the backend system. Is the host and system number correct?

Hi Göran

Thnks for your answer

This always has been happening, i´m thinking that this is a problem of Windows Vista Operating System, because one coworker has the same project and the same NWDS with the same SP but he has Windows XP.

I am working with Adaptive RFC Model.

I can´t logon in anyone backend system (R/3), because i can´t open de wizard reimport model...

well...

Hi Josue

I did'nt know that NWDS 7.0 was supported on Vista? But if it's not then you are probably right on your suspicion. Can you logon via SAPGui to your R/3 backend system?

Good luck!

HI ,

You can check for the function module in SAP R/3 whether its remote enable or not.

Second option is while trying import the model,check whether your NWDS is importing the model from the correct client(say 110 or 120).

3rd thing you can try:Try to import a model(some differenrt model which is remort enable ) from R/3 and check whether you are able to import or not.
