just starting to learn FM. After I finished designing the data model for an order/inventory system I stumbled on the problem very well described in this article:
Where I had designed on paper a table structure of Purchase Orders (PO), POlines, Receipts and ReceiptLines just like in the article.
When I entered them in FM I got an error saying I needed to duplicate.
I am just not understanding :-( Can anyone please be so kind to explain what is happening with this solution (as per the article) ? Just can't wrap my mind around it fmp_poLineReceiptLine.png
Thank you very much.
