To change the Invoice Run a funder is on:
Select Service User, then click Bill Payer.
Click Find, then select the relevant funder.
Select the invoice tab, from the invoice run dropdown, select the relevant invoice run.
Click the save.
Once the above has been completed, you'll need to regenerate the invoice run. The service funder associated with this allows the visits to pull through to the invoice run, ensuring that all visits have been reconciled.
