Updtable BAQ Custom Action on a particular row

In an updatable BAQ, I have created a Custom Action. I want the Custom Action to apply on the row that has been selected. I can’t seem to be able to find the selected row. Any ideas?

You have to modify something there is no way to see the selected row at the custom action BPM side

You would have to add a way for the back end to filter to the specific row you are looking to run code on. Generally people will add a calculated checkbox field and have that be available in a dashboard for editing. You would then check that box and run custom action you could cherry pick what you want one or many rows. An example of this would be the Min Max Safety Mass Update dashboard.
