Bex receivables report by days

Hi all,

I've created bex report which shows acc receivables by business partner on particular day. Since report aggregates all items from BSID and BSAD tables based on provided particular date variable, question arises how to show report by days or period of days, something like this:

I've could adapt structure of report and manually set past dates, but since my report is complicated as it is, is there any way to achieve this automatically?

Thanks,
