Smartconnect Map runs in one company but does not run in another company

So you created a map, run it to test on your test company and it works.

Then you run it on the live company and boom, nothing happens. Smartconnect just counts your records and does not import any.

In your mapping you have a GP Rolling column created. You need to delete it and re-create it with your mapping on the live company (this is defined in the companies window in the front). This will make the rolling column look at the correct company.
Re-run integration and it will work now.
