Book Control Cost Centre

Hi

we have set up in book controls gain/loss and clearing accounts for when we retire/sell assets, within this there is a cost centre also set up in Account Generator Defaults.

When we retire an asset, the gain/loss and clearing journal is picking up the cost centre from the Account Generator Defaults and we are having to then do a journal to move them to the cost centre the asset was originally purchased against.

I am trying to get the system to use the cost centre the asset was raised against when it creates the journal, but I am having no luck.
