R12.1.3 AR Transaction Form - Make Reason field on Reference Information Tab Mandatory

Hi,

We are using R12.1.3 with RPC5 applied to it.

I am trying to make the "Reason" field on the AR Transactions form mandatory - form details:

----------------------------------------Current Form----------------------------------------Form Application : ReceivablesForm Name : ARXTWMAIForm Path : /oracle/SUPPweb/apps/apps_st/appl/ar/12.0.0/forms/US/ARXTWMAI.fmxForm Version : 12.0.129.12010000.66Form Last Modified : $Date: 2015/08/19 01:29  $

I have set up the Personalisation as follows:

With a single Action:

However - when raising an Invoice, not a Credit Memo, the Personalisation also fires, and I can't then proceed to the Lines because the Personalisation says the Reason should be entered, even though the user cannot access the Reference Information tab:
