Filter Employee by Locked Indicator

Hi there,

I am trying to filter employees in a call from odata or webservice. However, this filter must have to be based on the user locked indicator, as the screenshot below:

So the question is, how can I filter an employee based on this field if I do not have it on the employee BO. I tried with LifeStatusCode, but does not work.

I know that the name of that field is UserLockedIndicator from the BO IAMUsrListController. Is it possible to have access to this BO?

Thanks in advance!
