I have a database that I have created using the Starter Solution "Invoices". The database has an Invoices table and a related Invoice Data table. I had created several table occurrences based on Invoices, but recently moved them to Invoice Data because I needed to work from individual order line items. Anyway the Invoice table had a very nice sort function using the sub-summary part and I copied that function over to the Invoice Data table. Works great!
However, the sort properties shown in picture revert back to the Invoice Table when I close and re-open the database???
How can I prevent this?
