Discussion board where members can learn more about Qlik Sense App Development and Usage.
I have an app where there are more than 100 variables mentioning the same column. I would like to change the name of the column in all these variables. Is there any way to do this in one shot?
Hi Mohammad, check in configuration -> Expression preview (CTRL+ALT+E), there you can change many expressions in one shot.
Hey. As far as I know, the expression browser does not display variables. You need to use the rename fields through the mapping table.
Look at here: Renaming fields using variable
where do i find configuration?
Press CTRL-ALT+E and the dialog will open.
You can look for expressions and use replace to change the name of the column.
I m using Qlik Sense Server. How to do it in the browser?
Ops, sorry, I thought it was a QlikView question, I don't know any similar utility in Sense.
Just to give some tips I use to centralize management of expressions:
- Using the master items.
- Using variables. As a simple example:
LET varName='[Column Name]';
Then the expression can use the variable, switching the variable in one place and all expressions using the varaiable reflects the changes:
Sum($(varName)) // It's the same than write Sum([Column Name])
