Hi all,
I have one RFC need to be reimported as modification in import parameter sturcture. After do that, I re-build all Model binding for this RFC. and it's work when I run the application. However, I found Null Pointer exception when I run other RFCs which have no change in the same project. I guess the problem is due to invalid binding for other RFCs as I fixed it before by rebuild all Model binding and related Content binding. It's not a easy task..
Does anyone have suggestion to prevent this problem or fix it? Thanks.

Hi Jack,
Have you invalidated the ARFC Cache? There is a known "feature" with RFC based WD models when you make a change to the interface signature in the backend system, that can cause issues when you re-import and then run an application.
Whilst I've never experienced the specific problem you are describing, of changing RFC A but RFC B failing, I still think the first thing you should do is resolve the ARFC Cache.
There are two ways of doing this - restart your server which will completely clear the cache or use the SAP delivered application to clear specific entries. See here http://www.google.co.uk/url?sa=t&rct=j&q=&esrc=s&frm=1&source=web&cd=2&ved=0CGMQFjAB&url=http%3A%2F%... for more info.
Gareth.
