Change fiscal year variant assignment - K0 to K4

Hi,

I would like to change the fiscal year variant assignment in company code.

We currently use the standard variant with 13 periods per year (K0) and now we are changing to K4.

There are several documents posted in this company code.

So please advise of any adverse affects that has to be considered and provide me some tips and areas to look up for.

Thanks and Regards,

Fernando
