User field Value without decimal

Hello Guru's,

I have created user fields for WBS in our project. In the value when we are entering any number its showing decimals also.

Want to remove the decimal for the value field only. The data is going to USR06 field. Actually we want to maintain Asset No. for that field in WBS.

Will you please help me to solve this problem. If there is any existing thread available for this you can mention that also.

Regards,

Amlan
