Carry forward of Open Items - FMJ2

Hi,

We are using BCS in EHP 7.0. i am trying to carry forward the open items with FMJ2 and Availability control is "Update without check". When i execute the transaction, system is carryforwarding to next year without any errors.

How ever, if i see the availability report FMAVCR01  for 2015-

Budget for 2015 is 0 - Consumable budget - 0, Consumed Budget is 20000$ and available amount is -20000$.

Where if i add the budget for 2015 of 50000$, then consumable budget - 50000, Consumed is 20000 and available amount is 30000$. it is consuming from current year.

Please help me on this.

Regards

Sam
