Quality Inspection in EWM - Partly accepted scenario

Hello Everyone

I need help regarding partially accepted scenario. For example out of 10 Cases/Item XYZ of qty 10, 4 are good and remaining 6 are not good. Business wants to accept only those 4 and return remaining 6. In this scenario, how do we configure the follow up actions? Do we get item/quantity wise updates form ECC? I have maintained quality score 50 against decision and assigned below PTWP action to it. Whenever that decision code was used in ECC, it is properly updating inspection document in EWM. But EWM, is making the 100% qty as Accepted with follow up action PTWP.

1. 1.      Do we need results recording in ECC for this scenario?
2. 2.      Do we need to implement any BADI to select which Case/Item can be accepted/rejected?
3. 3.      Is HU mandatory for performing QI in EWM?

In the EWM system, I could not configure more than 1 follow up action for a decision code.

Thanks
