Cash drawer total in grater than report total

Dear All,
I have found one issue. At end of day, total sale in Cash Drawer is grater than Grand Total Amount in WorkPeriod Report.
I suspect that some order from Client PC is not fully updated to server but KOT and BOT are working properly from Client PC.
My Question is that
Where can i check those missing order from client pc?
How can i adjust cash drawer amount and workperiod report amount same?
Respect,
MD Hasan

Start with showing your report.

Do you use preorder tickets/layover ticket in system?
