Got error of Fiscal year

Hi,
When I am submitting a Purchase Order, I got an error, shown in the image.


How can I resolve the issue?

Make sure you have the current Fiscal Year created and set correctly:

I got the solutions. Actually, the company is not added into the Fiscal Year. So, I simply added the company in the current fiscal year.
