LPL - Granting Update action access to only two specific user fields of a Business Class in a Securi

unknown

Good Day,

We have added two user fields to the JobRequisition business class which are added to a form that we wish to be made updatable when a requisition is in OnHold status without making the rest of the fields updatable. Of course, the following works well to open up everything:

JobRequisition BusinessClass
   is accessible
      for OnHold.Update
      unconditionally

But I tried the following to no avail:

JobRequisition.UserFieldXYZ Field
   is accessible
      for OnHold.Update
      unconditionally

I also tried the All Fields for JobRequisition Business Class excluding... but that didn't work either. The users have inquiry access to the business class while in OnHold status from another security class, but these lines being the more permissive security should trump that, right?

Thanks for your help!
