You can use the Quick Find in the Budget Tab to display Parent Budget Item: Available information, or simply not include columns from the Parent Budget Item.  

Alternately, if you would like to add this column, you can do the following:  
1.       From the Organizations tab, search for an Organization and zoom in on it.  
2.       Select the Budget tab. An error appears.  
3.       Click OK on the error.  
4.       Right-click and select Find in the grid. You will see the search in the Quick Find window.  
5.       Click Advanced and manually update the query to include the table name. If you selected one Organization record, edit the query to start with "Budget_Details.Organization_ID =". If you selected multiple Organization records, edit it to start with "Budget_Details.Organization_ID IN".  
6.       Perform the search.
