With C4C you can schedule MDR only once a day.
Here is a workaround to make them hourly
Create you BO with the required action. In my case the instances of the BO are created via an event on a standard BO under certain conditions:
Create the query for your BO. In my case the query uses the “processed” parameter as selection input.
Right click on the BO and generate the MDR object. Then generate all the screen and attach the screen on a valid WOC.
Assign the WOC to your username and schedule one daily MDR for each hour
