MIGO POSTING ERROR

Hi Experts,

I tried to posting MIGO it show error posting only possible in 2015/06 and 2015/05 in company code

So,I followed some instructions and suggestions by changing periods in MMRV but it again shows error

In OMSY in changed periods but it was not changed and shows error like your company code no longer initiated.

Please help me how can i solve this issue.

What periods should in considered

My Fiscal year is 2015 Apr15 to Mar 16  Fiscal year variant is C2
