when Personilizations added on AP invoice Form, with Message Type as 'Error' application is not allo

Hi There,

We had a requirement to do Personalization's on AP invoice Form, So that application should only allow one cost centre across the lines/distributions and when multiple cost centres are used then personalization should not allow invoice to be validated

when added personalization on AP invoice Form, with Message Type as 'Error' we are noticing a strange behaviour of Invoice work bench, its is not allowing us to update any distributions for corrections.

And when the Message Type is selected as 'Warn' the invoice work bench behaviour is normal and allows for the changes, but as its just a warning users are able to validate the invoice, the main purpose of having this personalization is failed.
