I was getting a Similar error however since it was the 1st of july and changes need to be done i did them anyway. I was still able to edit the tax tables and make the necessary changes so I ignored the message that I need to purge the tax tracking or summary since I already did that. And yes I do have 2 furture invoices that have not been clear off due to a key punch error and wrong date was put in. Will this cause a problem that I ignored the message down the road and Should I still try to run future date day end to fix the this for next time?
