Hello,

When entering new expenditures in the project plans, our users are required to enter the invoice number and the supplier. However, it happens that two different suppliers issue invoices with the same number, and we are therefore blocked by the tool, which does not accept two expenses with the same invoice number. How do you manage this situation?
We are also considering the possibility of adding a prefix to the invoice number, but as the field is limited to 20 characters, we are hesitant to choose this solution.

Thank you for your help!
