Location field on Purchase Requisition - How to remove the default value

Hello Gurus,

could you please let me know where is the setup (or profile option) not to show a Location value by default when you click on the Line Item in a purchase Requestion or Internal Requisition.

I know that the value is coming from the Employee file, Location field.

However, in Oracle 11i, even though there is a location in the Employee file, there is no Location that is coming by default in the on the purchase Requisition.

Please see attached screen shot.

Thanks a lot for your help.

Regards

Philip
