in different variants (with and without (), with and without = before the formula). The formula window tells me 'OK', but the result is not displayed (displayed as null).
I cannot use the field with the date of the last order directly in the dimension with the month name, because when i'll manage this, I need to add several more measures to the same pivot table that use other date dimensions.
No, I can't, because I need conditions. last order date is not the same as date, these dimensions have a different data array. in any case, I abandoned these calculations, since I never found a way to implement this in qlik sense. Thnak you anyway
