# How Do I Avoid Automatically Setting Fields to Uppercase?

Model attributes that are also key fields are automatically coerced to be in uppercase. You can block this behavior on a field-by-field basis by defining the `notUppercaseFields()` function in your TabMenu's user exit file to return an array of field names that should not be converted.

Example:

    			function notUppercaseFields() {
    			   return ['ELEM_ATT$AT_NAME']
    			}

You can also provide a global override for an entire TabMenu by setting the `shouldNotAutoUppercase` variable to `true`:

    			var shouldNotAutoUppercase = true;
