How to check the internal order budgeting as year dependent?

Hi, Can someone please help me out to find out how to check the Internal order budgeting as year dependent please?

Also, when we are posting allowing postings more than internal order budget given in the system? Means if we have given budget for Rs10000 we can do the postings of 11000. I have checked the settings in Availability control and everything seems to be fine. Please help...

Please reply urgently....

Thanks and Regards
