Order Reason to Order Type

Hello,

While creating a sales order I need to populate the drop down - Order Reason with a list of values which are present in my z table.

I have created my custom table with : Order type/ Order reason/ Description.

I need to populate the drop down with the entries which are present in the ordertype in my Z custom table.

I have found a User exit in the Include MV45AFZZ with the help of the thread :

http://scn.sap.com/thread/1804112.

But I am unable to acheive this.

Kindly share all your valuable thoughts.

Regards.
