Allowing a "blank" in a drop-down, peer single relationship

[ALW]

I have several drop-downs in my application that have a peer-single relationship. I want the ability for the user to change the field to "blank" or an undefined value. If I add a "blank" option in the reference attribute - it will show in the drop-down as "undefined".

For example - I have a rep field - asking for the name of a rep. If they fill out the field and then later want to change it back to "no value - blank" - they cannot do this. Is there any way around me having to actually add a value that says "blank" or "unassigned"?

Thanks,
Amy

Can you not create a process to clear out the attribute and put a button next to the drop down?

Something like...

Process: Clear out attribute
Rule 1: FIND BO WHERE BO=ThisBO TAKE BEST 1
Rule 2: BO.Attribute=''

Yes - that will work but it is more cumbersome than I would like. Thanks for the suggestion.
