delete business object row at once

Hi Guys,
I’m working on a VBCS application and I have a requirement to delete all rows from a Business Object in one go (not individually). Could you please guide me on the best way to achieve this?
Is there a recommended approach using an action chain, REST API, or any other efficient method on business object.
we currently use a Groovy script in an object function to delete all rows from a Business Object. It works fine in development, but on production, we’re facing a critical issue:
If two users are working on the form at the same time, the deletion occurs concurrently, leading to unexpected data loss.
