I’m working on an invoice processing application in the Application Builder. I fetch an invoice by ID and then retrieve all linked invoice lines from a separate table using that same ID.
I’m displaying these invoice lines in a repeating element inside a form. Each line currently has its own save button, which means users have to edit and save each line individually. This works fine for invoices with a few lines, but becomes impractical when there are 50+ lines.
Is there a way to save all rows in a repeating element with a single button click? The invoice lines already exist in the database as linked records, so I’m updating existing rows rather than creating new ones.
If there’s no bulk save option, is there an autosave feature that could work here?
I’ve attached screenshots of my current setup.
