thanks to some great help I am slowly learning FM through building an ordering/inventory/sales app for my wife's shop.
So far have a Suppliers layout which I like and now started with a Purchase Orders (PO) layout.
The only piece I have right now is a PO layout with fields to give it a progressive number and select a supplier and status from parent tables.
I need now to tackle the filling of the PO lines.
For now I'd be content with having a list of the products carried by that supplier to choose from and add an order quantity and if needed change the purchase price (and keep the running total of the PO updated) OR if I need to enter a new product open up some dialog to do so.
What are the FM layout elements and techniques to study to achieve this?
I've seen a layout from Daniel's website I like but I'm still not able to understand which elements to use: poMockup.png
Thank you very much for any help
