Go To Related Record [Show only related records; From table: PortalTableOccurrence; Using layout: "Detail View" (PortalTableOccurrence) ; new window ]
Note that "new window" is optional here. you can use this step with your button to open a new floating window set to your detail view layout or, if you omit that option, you can change layouts in your current window to the detail view layout.
"PortalTableOccurrence" should be replaced with the name shown in "Show Related Records From" in Portal Setup... for your portal.
Phil, appreciate your help but I'm just stumped. I get hung up at step 2: "From table: PortalTableOccurrence" I don't see that option in the table list. I also don't see "Detail View (PortalTableOccurrnce) in the layout menu
to repeat: "PortalTableOccurrence" should be replaced with the name shown in "Show Related Records From" in Portal Setup... for your portal.
You'll need to create a layout for your detail view that is based on your portal's table and specify it as the layout used in this script step.
