Excel 2007 : Mapped dependencies and filtering?

Hi,

I'm working on a sheet for mapping and showing dependencies between it systems. See attached worksheet for a simplified mock-up.

system dependencies.xlsx

The sheet maps systems with dependencies to other systems using the "System" column as a lookup table for the dependency columns.

The idea is that the sheet should filter or in some other way, clearly mark affected systems when one of the systems has its state changed to "down" so that the user can quickly gain an overview of which systems are affected.

I know I could probably go through all the dependency columns and filter according to the downed system, but it would be nice if this could be done in one action.

I'm thinking something along the lines of a macro or script that is triggered when the state is selected resulting in the filters being applied for all the dependency columns. However I'm not that much into Excel (yet) so I'm hoping for an easier solution.

Can this be done in Excel 2007 and if so how would you go about doing it - what tools or functionality would you use in Excel?

Cheers

Mark

Update: Replaced picture with worksheet

To best describe or illustrate your problem you would be better off attaching a dummy workbook, the workbook should contain the same structure and some dummy data of the same type as the type you have in your real workbook - so, if a cell contains numbers & letters in this format abc-123 then that should be reflected in the dummy workbook. Don't upload a picture when you have a workbook question. None of us is inclined to recreate your data. Upload the workbook and manually add an 'after' situation so that we can see what you expect. In addition clearly explain how you get the results..
