FBD1: "Run date" area - last date of every months

Hi,

I'd like to know if SAP can automacally choose the last date of a month.

For example, if my first run date is 01.02.2009 and my last run date 01.06.2009, and if I want my recurring entry be launched in the end of each month (i.e 28th for february, 31st for march...), what date do I have to enter in the "Run date" area?

For instance, what happens if I enter 31st in the "Run date" area although the month finishes on 28th (for february) or 30th (for March)?

Thanks for your help,

Regards,
