Change fiscal year variant - year dependent

Hi Experts,

My client has a fiscal year from July 2014 to June 2015.

It is using a year dependent fiscal year variant. And the year shift that I use is 0 and +1.

We have made an issue when defining the fiscal year variant to 2014. That is the year end dates to be from July 2014 to Dec 2014 we have to define in 2014 variant are defined as dates from July 2013 to Dec 2013.

Since already the postings are made to Jan 2014 to June 2014(since we use +1 year shift), I can't change the fiscal year variant dates now. 

Is there any solution to sort this out?

Thanks

M.K.
