I am getting an error when trying to delete an On Hold AR Invoice that’s created from a pro forma invoice. See below. The message seems incomplete and makes no sense. I need to recreate the proforma invoice to factor in the updated bill rate.
Does anyone know why and how to resolve?

BTW, is deleting and regenerating the pro forma invoice the best way to correct billing rates? In my example, some rates have been changed and added in the rate table after the proforma invoice was processed.
Thanks for your time and input in advance.
