If you've already invoiced a project but later changed the budget structure, you will need to edit the invoice to match the newly created budget items.
Note: If you deleted some budget items from the budget that were already invoiced and replaced them with new ones, you will see a "DELETED" label in the project detail. This label will disappear once you edit the invoice and reallocate the amount to the newly created budget items.
How to Reallocate Amounts in an Already Issued Invoice
Open the invoice and click the "Edit" button.
In the second step of invoicing, check the box labeled "Show all items" in the upper right corner. By default, invoiced items are hidden, so ensure this box is checked to display everything.
Set the old (original) budget items to zero, then uncheck the checkbox of that budget item
Select the new budget items created from the updated budget and allocate the corresponding value to these new items.
Important: You must maintain the same total value for the invoice.
Proceed to the next step.
Click on the "Generate from budget items" button.
Finally, click "Update" to save your changes.
