Hi. I'm a new QLIK sense user. I have run into a couple problems with field names recently. One problem is in loading data. I think maybe my column headers in my excel sheet are either too long or contain illegal characters. It causes an error and won't load my data. Then I renamed the columns in excel, and it loaded the sheet fine. Are there rules for field name length or allowed characters?
I've also noticed this problem in equations. When I use longer or more complicated field names in an equation, sometimes the equation doesn't work until I rename the fields. Any advice on best field names in QLIK?
