How to change the desription of a standard SAP field in the Search Help

Hi All,

Requirement is to change the description of the field WGBEZ60.The desription of the field is - Description 2 for the material group.

But the user want as - Description for the material group. He dont want 2 in the description.

we are using this field in the search help of Material group for the transaction ME21N and ME51N.

So please tell me how can we change the description of the field in the Search help.
