I'm using QGIS 3.10.0 A Coruna.
I'm using the field Calculator for an equation which requires a variable (which I Type in manually) and a (fixed) value within the same attribute table. This variable is different for each feature, meaning I have to write the equation (for my example) 55 times.
I dont have a problem with that so far; however, if for any reason my fixed value should change, I would have to repeat the work with the field calculator over and over again. Is there a way where
1) I can see which equation I used in the first place and
2) where I can automatically update my results in the attributetable in case the fixed value changes?
