I'm trying to start a POS solution but have already gotten stuck. I would have thought that you base the printed receipt on the multiple Sale items table, but I also have multiple payments, sometimes we even have multiple customers (max 2 people) on some occasions.
The files are arranged as below.
Sales Invoice---<Sales Items>---Stock Items
How do I set up writing the receipt? If I base it on Items I would have to create portals for Payments, or is there another solution as this seems very rigid. I have many transactions with 10s of receipts with multiple payments and 10s of items, but mostly (90% of the time) I have a 3 items or less and 3 payments or less.
I hope that I've made the question clear if not I'll try to re-phrase what you don't understand.
