Processing Value Dates in the Past 
Processing Value Dates in the Past
Value dates in the past result from items being posted in a period in which interest has already been calculated. This means that the last interest settlement will be incorrect, since some items have not been included in the calculation. To correct the interest settlement, the system processes these items separately.
The CPU date of the last interest run is June 14, 1997. On this date, we carried out the May 97 interest settlement. The next run is scheduled for July 12, 1997. An item with the value date May 25, 1997 is not posted until June 17, 1997.
From the date of the last interest run (CPU date), you can see that this item has not been included in the last interest run, yet the value date falls in a period in which interest has already been calculated.
