it looks like SC6Report is Nothing. Just put a break point and verify whether you are getting SC6Report instance or not ?

its showing null , what can i do now ?

_entities.SC6Reports might not have records for SC6ReportID so the .FirstOrDefault will return Nothing. You will have to make sure you have records for SC6ReportID in _entities.SC6Reports.

No you should not remove, Also your code should handle when there's no instance. See there's a check on IDSC6Reports = SC6ReportID. I think it's not getting satisfied for the SC6ReportID.

The problem here is you don't have the right data. Please make sure you got all the data and also fix the code to handle when you have no data.

Try debugging your source code to figure out where the error occurs.
As the error suggests, an object is null.
