Hi @Nagah.khaled 

unfortunately, there isn’t a function which can do that. I need it also.

Maybe you can create a new “Idea” for this.

I would normally do this:

Create a Base Profile and assign it to all users.

Assign the Base Profile to yourself Tools > Options > User Profile

Go to supplier master data page. Amend the Properties (RMB Properties) to make the Custom Field visible on the Layout tab.

Assign the Base Profile to yourself Tools > Options > User Profile > Edit Base Profiles

Save the changes made to the Base Profile Tools > Options > User Profile > Save Profile

Now when the users log on they should see the  custom field.

Cheers,

Graham
