Show Item field on smar form based on Requisition BU

Hello all,

I have a question about the possibility to show or hide the field "Item" based on Requisition BU, in smart forms.

Currently, though personalization, if we put the value TRUE on the Visible, then the Item is displayed. But this will impact all our smartforms, and we want to avoid this from happening.

Any form of expression used, returned as False. And even going through "Partial Triggers" did not help .

Would any of you managed to successfully use a trigger for this field?

Regards,

Mihaela
