I have a sharepoint 2013 list with a few columns. With SharePoint Designer, I've created a external content type to get some database informations from Navision. I have 4 columns from a database view.
One of the columns is connected to the Nintex Forms. The other 3 columns are visible in the list overview.
Is it also possible to show the 3 columns in the forms view? The column "Nummer" is the external data column.
I think that information cannot be shown in form (also with standard SharePoint forms you haven't the capability to see associated columns from external columns (or also from more standard lookup columns), so, unless these information are retrievable also with a SQL/Web Request (it requires Forms Enterprise) so you can do an additional call passing the value selected in the field and retrieving other information, I don't think this is possible..sorry!
