How to populate the list values for Item status filed while creating an Opportunity

Hi Experts,

We have implemented SAP CRM Sales 2.1 in our Landscape.

I am trying to populate the list of values on STATUS field for Opportunity item in Ipad.

In Device we have standard field STATUS under Item.

1. This is a standard field(Not Custom Enhancement Field) and it is existed in the device.

2. For that i have to populate the List of Values From TJ30 Table( Field Name CRM_VRGNG ).

How can i do this, Could you please any one help me in this.

Thanks and Regards,
