MSS Leave Request Rejection Note Mandatory

Hi Gurus,

We have a requirement to make the "Note for requester" field mandatory when approver tried to reject the request.

Please take notes that I am using copy of standard Workflow WS12300111,

and Task for UWL is TS12300097.

I've tried to set a breakpoint in BADI PT_ARQ_REQ_EXIT_DISPLAY=>IF_EX_PT_ABS_REQ~SIMULATE_VIA_BLOP

but it doesn't Triggered up when I reject the request.,

Is there any way that I can achieve this?

Thanks!
