posting period problem

Hi there,

While creating delivery document an error is coming:

"Posting only possible in periods 2008/11 and 2008/10 in company code ocgs."

while creating stock also same error was showing. however i have created stock in period 26.02.2009.

while creating delivery doc again the error is coming. Can it be solved or should i cancel the order?

i am unable to open the closed period. My company's fiscal yr variant is V3. And current period is 11 2008. in which i

have created stock.

Thanks in advance.
