Now it is possible to so this via the Part Invoicing option inside of the Invoice Creator.
Prerequisites:
This feature is only available if the EMT module is licensed.
Allow Part Invoicing Future Bookings must be set in the Server Setup > Financila tab.
Furthermore the new Dispatch Workflow Workflow must be used which contains Master Check Out and Master Check In and the Bookings have to be day based, so the items need to be booked with the Day Rates. Time Reporting can not be active for this to work.
This feature allows to part invoice monthly invoices (or invoices for a certain time range) setting any kind of days that you need to include inside of the invoice. For this to work, use the Part Invoicing functionality.
Invoice Creator:
In the Invoice Creator look for the Project to do a part invoice > right mouse click > Part Invoice.
In the *Select Items For The New Invoice* put inside of the Selected area the Booking in need to invoice. Use the new option *Partially Invoice Booking*.
A prompt will ask you to set the *Days To Invoice*.
Once put in the number, the blue link line [Partially Booking: xx Days] will show how many you have selected for this month's invoice.
Click OK on the window and "Confirm Creating New Invoices".
Send the invoice and then move the Invoice to the Invoice Manager.
The next time you want to do a Part Invoice for this Project, in the "Select Items For The New Invoice" you will see how many days are already invoiced right below the Booking to the left: Invoice xx days. Next to it *Booking: xx Days* and to the right a little note icon in which you will see an overview in the mouse over, which Objects have been invoiced so far.
This mouse over info is equal to a table:
Object Name: Invoiced / Remaining / Booked / Inv. Number
The feature won't stop you from choosing a higher number of days than actually need to be invoiced. So if my mistake too many days have been invoiced, you will need to remove the invoice flag of the part invoiced booking and you can start again.
