Current Month if the From and To periods in the Period range are the same, that month is used as the Current Month.

For example, when Period range is 6 to 6, the total expended is displayed for Period 6. 

When running  6 to 6  all other fields are YTD up to period 6.

When the From and To periods in the Period range are not the same, the period set as the Current Period in the General Ledger Profile on the Open screen is used as the Current Month for the display of the total expended.

For example, when Current Period is set to 8 in the GL Profile and the Period range is 1 to 6, the current month total is displayed for Period 8.
