Posting Error

Dear All,

I have facing the following error during MIGO posting.

"Posting only possible in periods 2007/02 and 2007/01 in company code 1000".

But before one day also i posted the document without any error. But now it come like this. I checked my posting date also.

I tried to initialize the period in MMPI also. There also i am facing error.

Kindly Help Me.

Thanks
