Derive Input Parameter Value from preceding Input Parameter
In BW there is an option of using an object called Variable with Replacement Path. The idea is that if I have two Input Parameters, once I select one Input Parameter manually, the second Input Parameter derives the value from the first one. In an example it would look like this.
1. User selects a Month in a first Input Parameter (visible to him through a Front end tool)
2. From the month selected in first Input Parameter, the Second Input Parameter (hidden from user) derives the last day and it is used as a filter for underlying Calculation view.
Any advise how to make it work?
