How do the sales document types "rush order" and "cash sales" differ?

For cash sales, you have to set a lead time for the requested delivery date of 7 days from today. For rush orders you have to I I set it for today's date.

When you save a cash sales document, the delivery is created automatically. For rush orders, this must be done manually.

For cash sales, the customer receives an invoice output instead of an order confirmation output. For rush sales, this is not done.

For cash sales, you have to use a billing type which will post to the appropriate cash accounts. For a rush order, you can use a standard billing type for invoicing.

For cash sales, delivery creation is not necessary. For rush orders, delivery creation is necessary.
