Fiscal year variant period incomplete (31.12) missing

Hi All,

Actually i have a requirement for fiscal year.

The year starts on 15th april and ends on 14th april.

1st Month April 15th to May 14th

2nd Month May 15th to June 14h

..... and so on

I have defined the fiscal year as follows --

Month Day Period Year shift

1 14 9 -1

2 14 10 -1

3 14 11 -1

4 14 12 -1

5 14 1 0

6 14 2 0

7 14 3 0

8 14 4 0

9 14 5 0

10 14 6 0

11 14 7 0

12 14 8 0

When saving its giving the error Fiscal year variant period incomplete (31.12) missing

Any solutions??

Thanks in Advance
