Hi,
You can only post special period entries in the March month only. However, at the time of report execution, you have to input this special periods along with normal periods. Suppose when you execute financial statement i.e.F.01, you have to select the periods for the fiscal year from 01 to 16, then it will display the data whole year. However, if you select the data based on posting date then you input the posting dates as 01.03.2015 to 31.03.2015, then it will display the data for periods from 12 to 16 automatically.
Hope you are clear now.
Regards,
Mukthar
