Reg : Show mandatory in LSO Reason Cancelation

Hi,

I have an requirement that I need to be set a mandatory for the LSO Cancelation reason.

In the TCODE : LSO_PSV2 in that reason for cancellation drop down is available presently we can cancel the reason without specifying the Cancelation Reason.

But my requirement to set the mandatory to the Cancelation Reason.

Kindly suggest.

Regards,

Sadiq K
