Super Back Flush Correction

Hello,

I want to know, how one can correct the Work Order superback flush process in any of the below scenario.

1) If user issued wrong quantity on Inventory issue screen.

2) If user now records the correct Hours in Time Entry screen.

3) If user not mentioned the correct completed quantity while WO completion screen.

Do we need to correct this using manual standalone application or any way to re update the super back flush process?

Thanks,
