An Error occurred before executing this process 'Marketing Effort Export Process: Error running marketing effort export. Object reference not set to an instance of an object - when running an export process
When running specific exports an error message is given about an object reference. This error is thrown when a query/selection or smart field that are referrenced in the export definition, having their name changed.
This issue is resolved in 4.0 SP6.
You should be able to export the Marketing Effort using another export definition. You might want to try creating another export definition with the same filters as the bugged export definition (if desired) and try using that.
If you need to find out which selection or smart field is causing this problem, you can delete one selection/smart field then attempt to copy the export definition or export the Marketing effort and continue doing so until you are able to successfully perform either operation. You might want to take note of the filters before you begin this process so that you can re-add them to the export definition after you've found the corrupted selection or smart field.
