In my application, I would like to insert virtually application user name to the column . Although I made all settings still when any user fill the form (even from different user’s mobile) my name (as admin) be inserted to the column. “=USERNAME()” is written in “app formula” field. Is it wrong place for “=USERNAME()” ?
AppFormula is always re-calculated/re-evaluated when an existing record is edited. Provided you don’t want the field to be re-calculated/re-evaluated, you have to use USERNAME() espression in the Initial Value field.
@Irfan_ERDOGAN In generally USERNAME() expression is not a good approach because quite often it will show it as a blank value. This is happening if the user hasn’t entered any name in his/her Google+ account.
If you want to use something, it would be better to use USEREMAIL().
