E-Business Customizations - how to execute a Form Personalizations when opening a Forms

Dears,

I am on Oracle 12.2.13,

i created a form personalizations, but it "works" only when i create a new line in the form (WHEN-NEW-RECORD-INSTANCE).

The goal of this form personalizations is to update automatically a DFF attached to this line (to give an information on a pending budget linked to this line).

BUT, i need that the DFF is updated every time i query the line, even if there are NO updates done on or in this line fields.

is it possible? And if yes, how is it possible?

Thank you in advance,

Kind Regards,

Philippe
