                            Hi,
you can use the action - execute the SQL procedure. In the configuration, you can trigger the query:
  update [BPS_Content]. [dbo]. [WFElements]
  SET [WFD_Description] = NULL
  WHERE WFD_ID = {WFD_ID}
In this case, all comments associated with the item will be deleted. The comments are saved in the database along with the information about the author and the date they were added. There is an appending mode here.
A long field with an append mode can implement a similar functional scope.
Best regards,

                            Hi,
while I would wise against using any kind of insert/update/delete statement against a BPS database, I also didn't find an alternative. 
In the SDK you only have the option to add read all existing comment and add a new one. There's no option to remove old ones, so there's no supported way.
I'm not aware what the EULA says to something like this, but I somehow doubt that using a write statement against the BPS database is supported.
Best regards,
Daniel
