I have a hard time figuring out what my date formula should look like on my items. Our suppliers deliver 2 times a week (tuesday and friday) so what I would like to achieve is that the customers would get the fastest delivery date. E.g. if a customer orders on a wednesday and our suppliers have 3 weeks delivery the formula would be 3W + 5WD but if the customer orders on a friday it would look like 3W + 2WD.
How would I achieve this when I cant put two different days in the same formula? Thanks!
