Vat Report on V11 Evo

Hi There ,

Trust you well .

Please advise :

1. New client on V11 having moved from Partner

2. The clients Box report and Tax Listing reports are considerably different 

3. When comparing by transaction type , it is found that the Box report is not handling the sign control correctly 

4. In gist basically both SINV(AP) and INV(AR) are both outputting as the same sign , which results in the correct figure .

Please advise if this is a glitch and if so what is work around or is there a simple way of changing the sign of each transaction type ?
