Currently, BW data gets refreshed from ECC system once daily. On the month-end days (which are not fixed days of the months) I get requests from the business to refresh data hourly. It's usually 2 days in a month but these days seem to vary every month. How can I accomplish this in BW without having to worry about running the process chain manually on the month-ends? Usually the business lets us know of the exact month-end days 15-20 days in advance.
