BADI_PIC_02 does not trigger when user clicks save in PIC01

Hi experts,

I was advised to used BADI_PIC_02 to carried out some validation in PIC01[screen:Maintenance of Full Interchangeabilities].

However, from my testing when I tried to insert records in PIC01 and clicks save, this BADI doesn't triggered as per wished.

The only time it was triggered is when user tried to delete a record in PIC01[screen:Maintenance of Full Interchangeabilities] and pressed save afterwards.

I am looking for a BADI/user-exit that will be triggered everytime the user pressed save in screen 'Maintenance of Full Interchangeabilities'.

Any idea anyone?

Thanks.

Regards,

Marlson
