ID parameter PRIOK for Notification

Hi dear all.

ID parameters are often useful. But sometimes it doesn't work, probably because it depends of the screen, or the moment, ... or other reasons I don't think of.

In fact, I am fed up with unreliable function : each time I propose that, I know there is a risk it will not work and I will not have the default value I am waiting for on my field !

Today my current problem is ID Parameter "PRIOK" (Priority on QM/PM Notification header), and of course, this one is still empty whatever I do on my own data from my user profile.

Do you have an idea in order to make an ID parameter working, when this one decides to not work ?

Thank in advance.
