In IN-A we usually are able to press F2 to search by user defined to find our old part numbers that since have changed.  
 
We use user defined for the old part number, since engineering is constantly changing our part numbers.  
 
In the new Drill Down menu in IN-A it lists the User defined on the screen but doesnt allow us to search by it.  
 
Am I missing something or was is taken out as a search field? If so, can we have it added back?  
 
It is very important for us to be able to search by user defined because its impossible to remember all of the part number changes.
 
Thanks a bunch!
