Controlling document not getting generated.

We have edited some FI documents thru FB02 for substituting Internal Orders. the IOs have got substituted, but controlling document has not been generated. By this the consumption of an expense is getting booked in FI. The same shud reflect in controlling too bcoz the budget is allocated to the IO there. Can anyone suggest how to proceed with the generation of corresponding controlling documents.. so that the expense consumption reflects against the budget allocated.

The volume being too high if anyone suggests a program or module which can take care of this need, it will be great. thanks...
