This is the link of my visualization: My dashboard
In the tab "Cursos por ciclo", I would like to know how to remove the option "PTJE.TOTAL" from the filter "CURSO".
You can do this by creating a new calculated field.
Now, right-click on CURSOR and select "create calculated field" then use this formula:
IF left([CURSO], 4) <> "PTJE" THEN [CURSO] END
Basically, this means: if the value does not start with "PTJE" then include it.
Then you can use the new calculated field as a filter, you will see that it does not include the "PTJE. TOTAL" value (it has been replaced with nulls now). So when you apply a quick filter the "PTJE. TOTAL" value won't appear.
Note: Normally I'd use something simpler like:
IF [CURSO] <> "PTJE. TOTAL" THEN [CURSO] END
but that is not working with your data for some reason.
