The ability to correct or amend nominal code, cost centre and or department when a transaction is in the deferred status.

I import around 90% of my data, from invoices to journals, etc. and most of the time I have future dated transactions i.e. periods still closed but with data in the deferred transactions status. If I notice that a transaction has been posted (in this case imported) with the wrong cost centre or nominal or department I would like to be able to go in and correct it. I actually do not understand what the amend or correct functions are there for as they have been completely useless to me so far.
