I have two global dimensions and have set up dimension combinations, where only several choices from Dimension2 list can be used for any choice from Dimension1 list. When I enter any transaction, the full Dimension2 list is showing in the drop-down choices. If I make a selection that is not allowed, I get an error message, which is the desired behavior. However, I would like the invalid selections not to show in the drop-down list at all. Is it possible to create such a filter?
