An enhancement has been included to allow a user to highlight multiple lines on a Job Costing Goods and Services invoice and move the group of lines up or down one position at a time within the invoice. The group position will be remembered when amending, printing or posting the invoice. The user must be aware that if the period is reselected then the whole invoice will be refreshed and return to the default line structure. To highlight multiple lines the user will click to the very left side of the line then drag the mouse down for the number of lines to be grouped for the move. Existing functionality for moving individual lines remains the same as the current process.
