message T4052 cash flow determined untill xxxxxx

When I create a savings account in transaction ftr_create and I go to the tab "cah flow" I get as message T4052, cash flow determined until 30/06/2014". But the cash flow should be determined at least till the end of the year. How can I do this? Or can I recalculate the cash flows periodically?

Please help me because I can't find an answer anywhere.

Thanks!
