User Exit / BADI to add new field to QP02 inspection characteristics table

Hi Folks,

I am looking for a screen enhancement to add new field to QP02 : Inspection characteristics table control.

Step1 : Enter tcode QP02

Step2 : Select the operation and click on Inspection characteristics button

I need to add a field in the table control which appears now on Change Inspection Plan: Characteristics Overview screen.

Program SAPLQPAA

Screen 150

Table Control TC_PLMK

As of now am not able to get any BADI for this.

I have seen some exits, but not sure which is suitable.
