ServiceDeskMessage/ChangeRequest variant

Dear all,

I have a question regarding the service desk message/change request. Under transaction dswp->

operations tab->service desk tab->messages tab, i believe

you will see the list of all the messages. My question is, just above the list, there is an pull-down text box with some kind of code. Could someone kindly tell me what is this code, and how we can customize/effectively use it?

thank you in advance.

rgds,

Yoshi
