Conditional Required Fields (SetCursorPos + ^)

When I need to conditionally set a field as Required I paste this code into my SaveEdit of the field I need to direct the user's attention.

 ^.Style = "";
If ZZ_REQUISITIONS.PER_ORG.Value = "CWR" And
      None(^.Value) Then
   SetCursorPos(%Page, ^, CurrentRowNumber());
   ^.Style = "PSERROR";
   Error MsgGet(14907, 1006, "Required Field", ^.GetLongLabel());
End-If;

This works just as well:

 &this = GetField();
&this.Style = "";
If ZZ_REQUISITIONS.PER_ORG.Value = "CWR" And
      None(&this.Value) Then
   SetCursorPos(%Page, ^, CurrentRowNumber());
   &this.Style = "PSERROR";
   Error MsgGet(14907, 1006, "Required Field", &this.GetLongLabel());
End-If;

The "^" will be replaced with the current Record.FieldName and Message 14907, 1006 is
"%1 is a Required Field".  In this example the Job Requisition is for a Contingent Worker, your optional condition will depend on your requirements.
