If a student deletes a class before drop/add, and then adds a different class, I suggest a Sales Credit be applied to the first invoice for 100%. Then, a new invoice should be generated for the new class. This is very neat accounting as each class has its own invoice and accompanying sales credit or payment or scholarship. I suggest this because recently a student added a class (3 credits). Then he dropped it and added a class that was 2 credits. Populi applied a sales credit for 1/3 of the original invoice, and then applied a scholarship to the remaining 2/3 of the invoice. To me, this was poor accounting because the original invoice was NOT for the actual class that the student took that semester. The original invoice should have been brought to 0 with a sales credit for the full amount, and then a NEW invoice generated for the NEW class.
Thank you for your time.
