FPCD Disabling Authorize button

Hi Experts,

I have a requirement in FICA. If the users are clicking Authorize button in FPCD transaction more than once, transaction is completing with blank Authorization Number.  So I need to deactivate / disable the Authorize button once the user clicked the button.

How can we to do this? Is this requiring a code change or Config change will be enough?

Or is there any other way to  handle this?
