Display Activity Code values in schedule only, not "empty" bands

Hi,

I have 5 Activity Codes assigned to the activities in my schedule and these are all included in the Group By column of the Group and Sort window. The last Code is “Discipline” and one of it values is “Cable”.

Within the Cable node in the schedule I want to have a further level with values of “Install”, “Terminate” and “Test”.

The problem I have is that when I create the new code, “Phase”, and assign these codes to the cable activities and include the new code in the Group By column of Group and Sort I get “No Phase” displayed within every node, except “Cable”, which has the headings Install, Terminate and Test, as expected.

I have checked the “Hide if Empty” box in Group and Sort but still get the same thing.

Is there any way to show this new code for Cable only?

Thanks very much

Dave
