I've ran into this issue and followed the instructions. There is no data damage or issues with the company file after running verify data and rebuild data. Both the Balance sheet Net income and the P&L statement show different totals. I'm at a loss as to why it's not matching. I can only get it to match if I run the P&L from the beginning of the year till the last day of the month and the balance sheet set at the last day of the month. I used to be able to run it the P&L from say March 1st to March 31st and the Balance sheet to March 31st and the net income would match. Now or does not. This seems to have started in Feb. 

Any ideas what to do now?
