Displaying the Bill Number as -1 when the Bill is Opened in the Wolvox Restaurant Program

When a new bill is opened in the Wolvox Restaurant program, which is used with the branch system, the bill number is ‘-1’ and when the account is to be closed, the “Bulk Sale Bills” window opens. 

This is because the hyphen (-) or (_) underscore characters are used in the “Branch Code” fields in the branch records. 

For the solution, these characters must be deleted in the relevant branch codes and the branch code will be changed.
