Use two subforms.
Code:
Function 1 | Responsibility 1 | Action 1
| Action 2
| Responsibility 2 | Action 3
| Action 4
The | mark indicates a subform.
So, you have a parent form whose record source is a list of unique Functions (and their ID's/Keys). Immediately to the right of the Function control you have a subform whose record source is a list of unique Function-Responibility combinations(and their ID's/Keys). Then inside that subform, immediately to the right of the Resposibility control is another subform that has a list of unique Responisbiulity-Action combinations(and their ID's/Keys).
Each of these subforms has a parent/child relationship using the ID's/Keys so that the subform shows the appropriate records.
