We are in the middle of a new implementation for a customer and they want to use Fiori, but have the apps filter data based on plant/site. From what I've read online this cannot be done without changing the app code to allow the filtering, is that correct?
Also, I thought perhaps we could use the filter bar to allow users to filter the output on their own, but some apps (Orders from Requisitions for example) do not have a filter bar implemented. Can the filter bar be added easily, or would that require a code rewrite as well?
