Budget in SAP

Hi,

I am using budget control for Internal Order/WBS and it is working fine.

But assume that i create Internal Order without any budget even though my company policy is to create budget, i am able to post actual cost.

Is there any way in SAP to control that if budget is not given to Internal Order no cost should flow to it.

If there is no option without budget Internal Order/WBS can be can be operated.

Bye,

Ramesh
