Does anyone know the Internal/Field ID for the transaction Date column in Expense Reports?

I know the Date ID in the "top white" section where employee name, due date, exp. rept #, etc is

I need the internal ID for the Date in the "report" section below - where the employee inputs the Date of each expense, category, memo, amt, etc.

Another way to explain what Date I'm asking about is, in an Expense Report, click Customize Mode>Sceen Fields>Expenses Tab>Date.

In any view, I don't have an option to click on it to view the Internal ID/get a description and it's a NetSuite default that has to be on the report.
