Suppose that in a pivot table or straight table, you create an expression and you label it as nsv_one_year_before. By default, The column heading will show nsv_one_year_before but in the "Presentation" tab you can change the column label, say -12 months. If you go back to the "Expressions" tab you will find with surprise that the expression label has been changed as well. Needless to say that if they were other expressions depending on the one that has been changed you will lose the link.
In view of this I can't understand why the column heading must be the same as the expression label, when they are 2 different fields for each item.
As far as I know it's only one 'field'/setting but there are two places to change the setting. Change it in one place and you'll see the change in the other place as well.
Thanks Gysbert, that's what I noticed. So should I understand that there's no way to have in the column heading something different than the expression label?
