User created a duplicate vendor bill and the same bill number is needed for a different vendor now. What can be done to resolve this?
To avoid this issue in the future, the Global Settings option for allowing duplicates should be turned off. As a workaround for the existing vendor bills, you can manually enter the initials of each vendor along with the bill number for their respective bills. For example, AB-85 and DE-85 for the two vendors. This ensures that the bills remain unique, despite having the same number.
