The Quick Pay Checker records up to 10 iterations of the target system for the particular period under test. 

By following the Quick Pay Checker test methodology you can significantly reduce the number of iterations required. 

Details of each iteration are held in the Quick Pay Checker and Reason Roll-Forward is applied when generating new comparison results.

This means that if the same difference is found when compared to previous results then the previous reason is automatically assigned. This helps prevent users from re-examining the same issue.

The process is repeated until all the remaining differences have acceptable reasons assigned. The parallel run test is now ready for sign-off.
