HI
Sorry, i do not understand what is the matter.
For my part, I can hide by profil each of them.
Please explain with attachement.

Hi,

please find screenshot attached. i would like to make visible "charge estimé only to certain profile, but not "charge reel" & "reste"

You have to play with item Ticket_WorkElement (not directly ticket)

Perfect thanks it works.
But i have an issue...
Fields becoming invisible for such profile are no more appearing in the bottom screen (details), but this profile is still able to add those data as column in top of the screen (list of tickets), it is a bug right ?? Please find attached screenshot for details

Or mayble is it possible to lock column management of screens for certain profile???

Once already used on list columns, these fields are not automatically removed.
If user clears definition (reset the dzfault list display), he won't see the fields anymore.
You can remove for users already using these fields with SQL query

delete from columnselector where objectClass='Ticket' and idUser=[id of the user];

If user reset the list, ok fields are disappearing but he is still able to add them again...
They are still available in column selector...
How to proceed?

moreover and to be clearer, i do not want that some profiles get this kind of information that is why it is not visible, but it has not to be available in column selector for that

Yes, this is an issue. Hidden fileds should not be selectable in columns selector.

But more security, to hide work and/or costs, use specific access rights "Work visibility" ad "Cost visibility"

Ok so as you say it is an issue, will it be fixed?

Where to find specific access rights you describe?

Found. All users are "Aucun visible" except Administrator
So it does not work ??

Of course

Where to find specific access rights you describe?

On screen "specific acces rights"

Found. All users are "Aucun visible" except Administrator
So it does not work ??

I just tested and it works correctly.
Be sure to save configuration of screen.

IN WHICH VERSION WILL YOU FIX IT?

i did ni change to specific access rights screen, it was already setup with "ucun visible"

In next patch (V7.4.2)
