Using a portal to display records in found set
I am trying to create a portal to display the contents of one field in a found set, while omiting duplicated values. E.g. There are 214 image records, and each has a 'folder' reference. 25 from one folder, 32 from another, etc. I'd like to display in a portal a list of folder references omiting the duplicate values. Maybe a portal is not the solution, as it does not allow me to display results from the same table. Suggestions?
I wouldn't use a portal for that.
A list view layout where the body layout part is replaced with a sub summary layout part "when sorted" by your folder field could be used to list the records and get one row of data for each folder. This requires sorting your records by that same field.
