insufficient days given for a Calendar period

[nagaramesh]

Hi,

can any one tell me v can define the calendar period as following...

Novermber Month I have given only 25 days and december 31 days only.

When I define the calendar as above it is completed with warning stating that No of days given in November r wrong.

so Can I ignore the warning msg and continue my ledger setup or is thr any other alternative?

Pls suggest me

regards
