When formulas refer display names or mapping names, the names should not contain any of below characters if the names are not quoted by double-quotation marks "":
"~", "`", "!", "@", "#", "$", "%", "^", "&", "*", "(", ")", "-", "+", "=", "{", "}", "[", "]", "|", "\\", ":", ";", "\", " ' ", "<", ",", ">", ".", "?", "/"
Examples:
- Expression @Customer#; will cause a syntax error. But @"Customer#" is ok.
- If a field has the display name Category.Measure, when adding it to a formula, quote it as
"Category.Measure" or "Category"."Measure".
