Change default message type for change request from SDCR to ZDCR

Hi Expert,

I need to change message type for change request.

I was created ZDCR message type copy from SDCR.

Status profile, action profile, date profile and text det profile was maintained.

But, when create change request from SLFN, default change request message type is SDCR.

How to change it to ZDCR?

Thanks
