I am quite new to File Maker, however trying to develop some solution.
Here is the situation I am trying to find a way out of.
First thing, I am trying to alter the Invoice starter solution to get the required result.
I have a number of tables. They are:
- Invoices, and
- Invoice Lineitems
There is the Invoice Details layout based on the Invoices table. I have located the main portal at this layout, which is related to the Lineitems table. I use a popover button and another portal to select and add lineitems to the main portal. This selection portal is linked to the Projects table via a relationship as shown at the screen shot below.
The question is how do I set the portal filtering so that after a project is selected in the popover portal, added and appears in the main portal it disappears and is no longer shown in the popover portal?
Many thanks in advance.
