Exclude Commissions Field is Missing in the Drop Down List When Creating a Transaction Saved Search

Although Employee Commissions feature is enabled, Exclude Commissions field could not be selected in the saved search as filter as it is not in the drop down list for selection. The reason why this field is not available on the search is because you need to have another feature enabled. Navigate to Setup > Company > Enable Features > Transactions tab and set Alternate Sales Amount = T.
